25th Anniversary Edition Ton UP Machine CB750K

Well, next year will be my 25th Anniversary of creating machines over on this side of the pond, many people have asked would I replicate the infamous K5 with Cafe on the tank to celebrate a quarter of a Century building Motorcycles, and I thought, I may go along the similar lines to that very Bike that kind of put me on the map so to speak.

But what should I do?  On reflection I think it is indeed a cool idea to do something like that very machine but, with some extra cool parts and exhaust system etc but I do have a NOS Paul Dunstall 5 Gallon Manx Tank in my Barn and will probably use that, so, I have a few old parts laying about and have been to and throw in coming up with that popular concept bike I created all them years back.

I have an empty Motor that I will use as a mock up for the time being. Then build something that will have a bit of oomph, but we shall see how things go, but the amount of messages I get about the old Cafe Bike I created all them years ago, still causes a stir and I think it will be fitting to do something in that style, maybe different color etc and wheels too.

So I will use old snotty spare parts to mock it up, as well as some New stuff to see if it will fit and as you see, I think I may go with my Infamous Sidewinder Exhaust system as it hugs the frame and, you can still use a main stand. I am putting my Vortex Baffle in for that crisp response and crackle when you open and shut the throttle.

Simply slide the baffle in all the way and the endcap finishes the system off just like the old days and I like ceramic Black end to give a good contrast to the system.

Please remember, this is all a Mock up, I will strip the frame and then either paint or Chrome it, not decided what yet but will add info as and when I do more to the bike, I am just getting a feel right now but love the way it will sit and of course will use shorter fork tubes in the steering.

See how close the Sidewinder is to the frame, but, not touching it, and- If you look, you can see that if you wanted, you can still use the Main stand, even if you were changing a rear tire or fitting a new chain, it makes it easier to slip the main stand on and not have to remove the exhaust system.

Still so Much to do and see where I am going, but I do like my Sidewinder Exhaust system as on the 75K I created a quarter a century ago I went with a different 4 into 1 system, plus this system allows for super easy access to the Oil filter Housing too.

I love the look of the tromboning headers and they flow so well, a crisp note that will get you noticed every time you twist the throttle, the bike will get a complete strip down and then I shall bead blast the paint down to bare metal, grind any welds off that are ugly and add some brackets for New tank and seat combo etc, this will take time but don’t want to rush either.

This is my own design and I like to Ceramic coat these , this time I chose the Brushed Aluminum look and I think it will set the bike off great once everything is tied together and have that Cohesiveness that will draw a crowd.

Of course stopping power is paramount on these machines and with a little extra Horsepower, these inline fours need some good surface area to be able for the brake pads to grab onto and bring you to a safe stop, so I chose to go with Beringer and have the floating Rotor and Custom Caliper set up to give me that punchy braking that many lack on their builds.

Of course, you need a good strong Master Cylinder to push all that brake fluid down to the Caliper as quick as possible and I thought I may as well go for the trifecta and get a Bringer Master Cylinder set up and very cool it looks too.

As you can see, this is a rough mock up, no painting will be going on until I have completed the whole build up and then once I am happy I shall do the tear down, rebuild a Motor and then slowly assemble the machine, but right now I am trying all sorts of concepts, I had an old set of 1977 Lester Rims that came off an old Chopper bike that was parted out many moons ago.  It is a 19″ front and a 16′ rear, the shock absorbers that I have fitted are not tall enough for what I want, these are about 13 inches from center to center, I want at least 14 inch centers to raise the rear end for a more level stance.

I have had this old frame for years and its weather beaten, but that makes it for an interesting build as I love resurrecting 50 years old Motorcycles from parts, I believe this will be a fun bike to ride, I shall incorporate rear sets and maybe a Custom swing arm with adjustable shock mounts for changing rear Geometry etc.

So, although the frame is Rusty and some corrosion, I have always started with frames like this, I am media blasting it anyway so it will be all fresh metal again when I start the build up after I am happy with the overall look when I am done fitting parts.

I have other things to do like all my orders today, so I had better get the exhaust orders done and ready for the UPS driver as exhausts always sell well and weather will be warming up all over the globe soon and that means- Riding weather.


So, with that I had better get these orders packed and labeled for exhausts and get them done as light will be fading soon, but thanks for follwing me on the 25th Anniversary build and of course, I shall keep you all posted via here.

Honda CL77 unloaded and now in workshop.

I managed to get the old girl off the Truck and Now its at My workshop and will be a while before I get into it as I have a few projects I must try and sort out, its getting to be a bit of a cluster as I have a lot of bikes at the moment and will try and get through them when the weather cools off a little . right now its a scorcher but I shall get there.

I shall put the motor in at some point and will add other pieces when I take them out of the boxes that I picked up, no idea what’s there in its entirety but will plug away and see what we have, should look pretty cool though as it has great lines that flow very well for 1967.

Will look out for a few parts like foot peg rubber and wire harness etc but for now I shall put boxes on the shelves and the bike is in the Barn now with many others keeping it company.

Some of you may be interested in this build?  It really is something you wont really see around and is a great conversation piece for the enthusiast out there, but I will plug away when I get some time as it looks like it will be fun.

I will of course post anything that I do as many people ask what I am up to at the workshop and I thank you all for the emails and phone calls etc as well as texts about the parts and the bikes I am working on.

Picked up a 1966 Honda CL77 305 today

Today was a GOOD day, you know, when you find a penny and pick it up?  I had an email from a Client and he said he had an old Honda that had been in the family from new, its been torn apart a few times but was I interested in it?  I said of course, I love trying to keep old Motorcycles from going to the junk yard and drove up to the guys parents to pick it.

I asked who originally owned it with any back story, here is what he replied to me:

 

It was my Uncle. He returned from Vietnam. Bought the motorcycle rode it for 6 months. Put it in his parents garage for storage. His parents died 10 years ago sold their house and offered it to me. It had not been ridden since then until I restored it. Mainly rust removal. Mechanical clean up. I rode it around my block and put it away in my garage for many years. Sold my house transported it to my parents house where I restored it for the second time to the current color. One family owner. After I restored it the first time I offered to give it back to him for his granddaughter when she was old enough. He didn’t want it back.

So, with that I jumped into my F250 and made the trip up to Rancho Cucamonga before it got too hot as it would be well over 100f there after 10am, I arrived in good time and loaded the bike up, there was a tote box of parts and the engine was sat in the corner of the garage.  I loaded the bike up first, it has no shock absorbers so had to get the guys parents to help me push it up onto the bed of the truck, where I have a motorcycle chock and then strapped it down.  I picked the Motor up and loaded that and the box up and wished them all the best and headed home.

I have never owned one of these models, the scramblers were so popular and quite fast for the era and even though the color is not my cup of Tea, it’s great to get the bike and not sure what to do with it at this moment but it will go up in the Barn and wait until I have finished getting the workshop finished as Its hard to move for bikes in there lol.

But, it will be fun later as even though too much of this has been powder coated One color, I think it will look pretty cool once together and a few changes with a bit of Chrome here and there to break up  the Sea-Foam Green embodyment.

These are classic bikes and some how there is a Single seat frame attached as well as the original double seat in the parts pile, but, it reminds me of me and my brothers NSU quickly we had as kids or an old D1 BSA Bantam, so I think I will stick with the single seat set up as it does have a Brit Iron look to it.

The good thing about it being stored in a Garage and of course being Powder coated everywhere, is that it isnt rusty at all, just dust from sitting in one place, a rare thing indeed, and the original License plate with Original Tags from 1966, still has pink and registration in the tube that is affixed to the plate and numbers match frame and motor, so all good, another thing you do not often come across when you pick a machine up.

 

I had no plans on building another bike as I have about 12 other bikes in the Barn but eventually I will get to this machine and every now and again when I get stuck on another build, I can turn to this one, it will be fun, unless somebody out there is interested of course?

I shall be having fun creating something cool with it when I start to wrench on the Green Machine, as I can get parts still for these machines, they were a great motor back in the day.

  • Width: 32.3 in (820 mm)

The bike features air-cooled, four-stroke 305cc overhead parallel-twin cams. The gas tank holds three gallons. The CL77 redlines at 9,000 RPM, reaching a top speed of 85 miles per hour.

There is quite a following for these bikes.  The first CL77s were imported into the United States in 1965. They were a dual-sport version (then known as scramblers) of the CB77 Super Hawk, a 305cc overhead cam parallel twin. The Super Hawk had been on the American market since 1961, two years after Honda had established its import arm in Los Angeles.

In 1965, Honda finally decided there was an American market for a 305cc scrambler. Cycle World immediately tested the bike and liked it, even through it was not the production racer they had hoped for. Cycle World referred to the CL77 as a “gentleman’s scrambler,” stating, “It is, in fact, the appeal of scrambler-type styling that sells the CL77.” Period testers found the CL to be too heavy for competition and not as fast as the CB, but perfectly adequate for both offroad fun and reliably getting to work.

The four-stroke engine was almost identical to that used in the CB77 Super Hawk, with the same aluminum cases and chain-driven overhead cam. A lower compression ratio to aid low rpm power was allied to long, upswept pipes to assist ground clearance, and reliability was ensured by full-flow oil filtration.

Unlike the Super Hawk, which used the engine as a stressed member of the frame, the CL had a heavy duty single downtube cradle frame, topped by a small silver gas tank and protected underneath by a steel skid plate. The front brake was smaller in diameter than the one on the Super Hawk and the steel wheels were 19 inchers, with deep ribs to resist dents.  Large air filters and a battery were tucked up under the seat. The CB’s electric starter was omitted in the interest of saving weight.

 

So, a long way to go when I get into this machine but a fun one though and even though it does have the original dual seat, I do like the single sprung saddle to give it a more European look.

“In those days, a Honda Scrambler was a very desirable motorcycle, and it is still adequate for the job. You just have to keep in mind that it is only 305cc, and the suspension only has three or four inches of travel, and the brake gives you that Nostalgic feel of, ” the harder you press, the quicker you will stop” feeling.

Well, thanks for looking at this 1966 Honda CL77 that I have taken on, you can always email me questions at: carpy@carpyscaferacers.com or text at 714-598-8392.

Happy 4th Of July Everybody

Time sure does fly by and now it is the 4th July, I wanted to wish everyone that I know in the states a Happy Independence Day, Jenn has made an Apple Pie and the Smoker is full bore cooking some Hamburgers and Hot dogs to celebrate the day. Just some different fun stuff to watch on your day off.  HAPPY 4th Everyone.

I went out for a Pint of milk, Came back with 10 CB750 Engines

It’s a funny old world, I mean, I initially went out to get a pint of milk and on the way there I came across a stash of SOHC Motors that a buddy of mine needed to off load as he was clearing his place out for renovations etc, what better way of getting rid of them then to let me have them.  And, as I have a Long bed Pick up truck, I thought to myself I should be able to get all 10 engines in the back of the F250.

Lucky for me, it’s only 4 miles from my place, and as my old beast only does 6 Miles to the Gallon, it was well worth taking the turck to go and get these SOHC in line Four Motors, they had been sat outside in the Californian sun for many many years but I can use some of the parts even if some of the motors are locked up etc.

It was no easy task carrying 10 CB750 Motors from a back yard and loading them onto my truck, at 230 pounds each, every one became heavier and heavier, by the time I had dragged the 10th Engine out and up and onto my bed of the F250, i was feeling as weak as watered down beer. But I got them all on and then thought about it, man- That’s just over One Ton of Engines, and the F250 is a 3/4 Ton.

I know I will have use for these, even for parts alone, I have a small collection now that for now I shall place in my barn and wait until later on when I have some free time to see what is what.

These towed home no problem in my pick up and that hardest part was unloading a Ton of engines, as it was only 3 miles from my place and I was already tired from throwing tem up onto the pick up bed, but, not as far to move to the barn.  I sure felt it afterwards as thats 2 ton moved in less than 2 hours.

I have stored them away now in the Barn, but I am still working on New doors for the outside, so will just have to tip toe around for a bit until I am ready to hang the doors up.

Glad to have got them and I know I will be turning to a few when I create some more machines for the tarmac, nice to have spares at your finger tips though.

I have another Motor in a frame you can see and one more on a dolly in the shop that I need to move over, always something to do at my New location, it will take a little time to get it how I want but then it will be icing on the cake as working from Home is always the easiest and more enjoyable way of working i think.

I have a lot of work to try and catch up on since our European visit but refreshed and ready to take on another chapter in the life of Custom Motorcycle creation, I have a few ideas for more exhausts, Handle bars and other parts, so stay tuned to the site if you can.

Oil leaks whilst i was away need to be cleaned and gaskets fitted, Doors painted and hung, and then organise the bikes and where the parts will go is something that is not to be rushed but everyday there is something to mess about with and I enjoy so much.

Thanks for reading my posts, I like to share what I have been up to and its great hearing from you too and seeing what you are building at home, if I can help I always will be it via email carpy@carpyscaferacers.com or call / text at 714-598-8392 as its a pleasure having a chin wag where ever you are in the globe.

 

 

Picked up 6 CB750’s today

Sometimes I get a call asking if I could clear out a garage or back yard as it has a motorcycle in it, this time it was 6 CB750’s, so what closed the deal was it was free but a friend of mine I have known many years and helping him out was the least I could do, and as he was less than 4 miles from me, I took the big G F250 out there and loaded up and bought the bikes home. I dont like to have to many as the place gets jammed packed but, its hard to not when it is so close to home.

To be honest, I can never really turn bikes down, especially CB750’s as I have had over 150 of these over the years and parts are always good to have handy, so I could not say no to this fella and help him out of a predicament too, these were in the back yard of his place, so a huff and a puff as some had flat tires etc but, determination is always key here and I wanted to get these home to eventually be used as another build. Once I get the Barn doors completed I shall space in the workshop to haul these up there and find a corner to rest them up together.

I have always enjoyed coming up with another build, they do take time and of course money, but when you hear them fire for the first time in many years, its something you get quite a buzz from, I get many texts or emails from Builders and customers who tell me that they just got their machine to run and I feel so stoked for them as I understand the euphoria that they feel when they first time you hit the starter or kick the kick starter and the engine coughs into life.

These are getting harder to find in back yards these days, I remember at one point I had 25 CB750 Honda’s in my back garden and driveway about 20 years ago and I have built every one of them over the years, so I was quite stoked to have these and bring them home. But don’t want the place to look like a junk yard so have to hold back on other stuff I have been offered.

Nothing super rare like sandcast etc here, but a couple of K1’s of which I have always liked anyway as never was a fan of the Ko with the Big side covers etc, there is no rush to do anything with these 500 pounders, so just unload and put them up in the Barn later until I come up with a build plan for them.

I have spent a lot of my life with Motorcycles and finding new stuff is always fun, just bringing them back with a plan of getting these to be back on the road in one form or another is always a challenge that I quite enjoy.

I have some Motors to look at tomorrow, so who knows what I may bring home, the hunt is half the fun and even though they are what I call snotters, parts are always handy to have when building machines.

So now is the time to unload these and see what is there and then I can mentally remember what these are as I store them and know that I have a choice of frames and years if I get into creating a new Build that will turn into something head turning, its hard to refuse when you build motorcycles and parts for a living, some will get it, many will not and think its some disease etc. LOL!

Of course, if I do start a creation, I will be sure to post on the website and share with you lot as many of you ask what I am up to these days and I thank you for that, I will be making more new parts too, so keep checking back on the website to see what’s going on, I do like to post blogs too and give you lot something to read.

 

The Rocket Four Motorcycle I built out of a non running CB750 Four Honda back in 2007

Time does indeed scream by at a pace that I really cannot fathom these days, but I am glad there are such things as you Tube etc that keep videos that I posted all them years ago.

Here is the “Rocket Four” Bike that I created out of an old non running inline four, I love these 500 pounders and this was a great build that none were around at all when I did this, so it stood out, I have no clue where the bike is now but hope they had fun with it?

Fun days and The seat I made for this bike came on to be a best seller for me, sending over 500 of these Rocket Four seats all over the globe, quite proud of that to be honest.

HONDA Super Sport Comes to shop to get running again

I never know what may turn up at the workshop these days and this time I was surprised to unload a pretty clean 1975 Honda CB750F Super Sport , this has only 8000 miles on the odometer and is a one owner machine that a Customer just purchased locally and then bought it along to me to see if I can get the motorcycle to run and ride once more.

This Honda SS had been sored away for a while so the normal things will need to be addressed to be able to get the old girl to function once more and give the new owner miles of smiles.

The bike is pretty much as stock as a rock, the only thing missing is the big Cannon tailpipe and the side covers, I make the side covers so that will not be a problem but the tail pipe may be another story, but the bike has a tiny battery that is dead, I will need to order a New one for her to be able to get this girl cranking over, but I shall take one off one of my own projects to see if I can get the old girl to fire up again after a long slumber.

It really is in good condition for its age, remember , she is now 47 years old, and I expect her to be a little stiff in places and get stuck from standing in a garage all that time.

On inspection the Gas Petcock had a lot of Brown sticky old fuel around the lever, so knew that the carburetor would be in dire need of stripping and completely overhauling to give her a brand new life once more, as the gas in California is awful, and in less a month, fuel will start to go bad and tarnish the carburetors and also the gas tank inside, causing blockages inside the fuel journals and then I have to vapor blast them to get it all clean and look like a factory finish.

I had quite a task of pushing the inline four into the workshop, as the front brake was sticking like an egg in a pan with no oil, so to free the piston in the front caliper, you have to tap it with a rubber mallet, it tells me right away that the piston has rust spots from years of sitting in hot and cold temperatures and this stops the piston from letting the brake pads fully release.

So a full strip and rebuild will be necessary to get the old girl to move freely once more, I have no worries fixing this as its a common issue due to the caliper body being an aluminum composite and the Piston is made of polished steel, the piston gets small rust deposits on the outer part and catches the O Ring and wont retract unless you bang the caliper body with a Rubber Mallet, so all New parts soon and I can get that all taken care of.

The Carbs will be pulled but may try to run the old girl using a Lawnmower gas tank I rig up and run Fresh fuel through the tank of the the auxiliary jig I made and right through the carbs, as I fear the petrol tank has some rust in it and will need to clean that out too, but I will run the bike through the auxiliary just to make sure that the engine is running ok and no issues with gearbox, clutch and maybe check for any oil leaks from the cases or cylinder head etc.

Once I remove the carburetors, I can take apart, vapor hone, Polish and synchronize to get this inline four 500 pounder purring once more, these are great engines.

The airbox is always a royal pain to remove and refit but I have done it many times, just have to be patient to be honest and plenty of WD40 at hand to ease the parts out.

Eight Thousand Miles on the bike, that’s super low, just was not ridden much by the original owner and a great find to the new person that found it by chance, stoked for them, the display cluster is in really good condition and gauges are not broken or scratched either.

 

The year 1975 saw the introduction of three F models, the 400F, the 550F and the 750F. That 400F was truly trick, with mildly set-back footpegs, a flat handlebar and a lovely megaphone-styled exhaust. However, the company decided to go the conservative route with the 750, apparently more concerned with bringing four-piper types into the sporting world than with luring crossover owners from the Ducati realm.

This is partially a retelling of the making of the most significant motorcycle of the last 50 years, but it is a story worth hearing again. There was nothing new about disc brakes, electric starters and overhead camshaft, transverse-mounted, four-cylinder engines in 1969—just that Soichiro Honda had made them cheap and reliable. The CB750K was a winner from when it left the starting gate, but everybody knew that winners get old.

Which is when the styling artists got their orders. The K was OK, and would remain the mainstay of the lineup, but something snappier needed to be on the showroom floor. Not too snappy, mind you, not like a Laverda 750SF nor an MV Agusta 750S, but something to provide at least the image of snappiness.

Call down to the muffler department and tell them to make a four-into-one exhaust system. Have the sheet-metal guys stretch that gas tank out a little, not much, just a smidge to give it a slightly elongated, racy appearance; and hide the gas cap. Then tell the seat people to make a little fiberglass extension to fit the back of the saddle, sort of a faux bum-stop that some single-seaters had. The fast look was born.

Of course the frame and engine departments were given their chores. The chassis mathematicians figured that Super Sport riders would go a little faster than those on the standard K, so they gave the fork an extra degree of rake, to 28 degrees. Along with 3⁄4-inch more trail. And left those ugly gaiters off. Built a slightly longer swingarm, which added up to a 57.9-inch wheelbase, 6⁄10-inch longer than on the K. This meant that when the F rider was trickling along U.S. 2 in North Dakota at a modest 100 mph, the bike was reasonably steady.

Power was another matter. Honda did not necessarily like to advertise horsepower ratings, but dynamometers don’t lie—unless they are hopelessly miscalibrated, in which case it is not lying. The F put out a good 10 percent more ponies than the K, and while some of those 58 horsepower, at 8,000 rpm, could be attributed to the freer flowing qualities of the four-into-one exhaust, the rest came from a slight boost in compression ratio, using domed pistons, up from 9:1 to 9.2:1. And the timing specs on the valves had been altered to adjust to the new exhaust. Also the carburetion was cleaned up a tad, in those halcyon days before the EPA, with the best of intentions, made a botch of things.

The F, with a full 4.8 gallons of high test in the tank, registered slightly over 535 pounds on the scale. Which was 10 pounds heavier than a K, although the F had three less mufflers. Possibly a little extra metal had been included in order to strengthen the double-cradle frame, with triple tubes, a main and two auxiliaries, running under the tank.

Put the leg over the saddle, and the rider sat pretty high at 32 inches. Pull the choke on those four 28mm Keihins, turn the key, and choose between pushing the button or kicking the starter; 999 times out of a thousand, the button won. Vrooom! The muffler had a mellow, unobtrusive sound, the engine warmed quickly, and the rider was away.

Twenty miles down the road, the Bridgestone Super Speeds were heated appropriately, and the twisties began. Tire technology was still pretty basic 40 years ago, but the 18-inch rear and 19-inch front spoked wheels each had a disc. Hit that first sharp left hander at a rapid speed, and the F felt really good. However, coming back at the same speed, the corner now a right hander, there would be a Grounch! as the collector box located beneath the right footpeg touched down. A little help could be had by getting out the toolkit and maximizing the preload on the shocks, but even then, a 200-pound rider was going to mar the chrome. The owner of this CB750F has changed the shocks to S&W, a distinct improvement.

Other than that minor drawback, the F did live up to its sporty intent. It probably was the best-handling of the Japanese 750-plus fours of the time. And got better.

 

Only 2 weeks until Christmas day, time is flying by these days

The Clock is ticking and I have been busy filling orders and getting them off as fast as I can to get them in time for Christmas day, its a busy time of the year for all but I thank you all for your orders and repeat customers.

I have a busy year ahead of me with quite a few long time builds to complete and quite a few new products to introduce on my website.

To get your Sunday off, I thought I would add a video I watched yesterday, just to show you what is still hidden away in barns and shed etc.

 

Have a Great Sunday everyone.
