Fun times ahead at the workshop.

Well, a New year and New projects, I have a bunch of bikes that need to get running and then decide which way to go in the way of building and creating something cool from the shop but many different platforms are sat in the Barn, just awaiting some wrench time, but I do enjoy creating New rides.

I get many questions on how do I put in the Knee inserts on gas tanks, well, first off, I find a damaged tank, I don’t want to use a good solid undented gas tank, seem a shame to bash the crap out of it to be honest, so I usually have something about the shop or in storage that I can use and love to repurpose something that has been discarded, but I do use ear defenders as I have already got  Tinnitus from years of grinding metal, riding motorcycles with No ear plugs and going to many gigs and standing up front by the speakers.

I really enjoy making parts for the machines I build and of course offering it to customers too, its a noisy job but if it was easy, then everyone would do it right?

I have a few ideas for New parts this year, so keep checking back with me, also I hope to offer parts for different models and brands of Motorcycle, so I should be able to help you all, my Customer Service really is hard to beat compared to the many shops that have sprouted up recently, this is my career and my passion not just a business.

If its engine parts you need, drop me a Dime or Text on 714-598-8392 and I am more than happy to help you lot out with your project, this year should be a fun one and maybe I will meet some of you at an event?  I have built many Motorcycle over the almost 23 years I have lived here in Southern California and look forward to building many more.

 

The Hot Rod and Razor exhausts Now in stock, this is how they sounds too.

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.

 

Merry Christmas Everyone, here’s a blog on the Millyard RC374 Honda six replica

Wishing everybody a very Merry Christmas and thank you so much for all your orders.

Wanted to have a long blog with a few videos at the bottom of here to show you how skilled this fella is, I am sure you will enjoy the video’s over the Christmas period?

When rocket scientist and motorcycle madman Allen Millyard went to the motorcycle races at Castle Combe, he met none other than Guy Martin. Martin brought Millyard back to his pit area and showed him his replica Honda RC174. This was the bike that Mike Hailwood dominated the 350 cc class of the 1967 Grand Prix season on with its tiny inline-six engine. Millyard loved it, and Martin suggested that he should build his own RC174 replica, so he did.

In what seems like an act of sacrilege, Millyard started with a pair of Yamaha FZR250RR four-cylinder engines. The Yamaha engine was a better starting point than anything comparable from Honda because the Yamaha’s heads and blocks are symmetrical, making them much easier to add extra cylinders to than some of his previous efforts. He started with the heads, cutting the two outer cylinders off of one and cutting the other in half at the center. Already he could see he would have to rework the oil and coolant routing inside the engine. He’d end up using three separate coolant galleries inside the final engine to keep everything adequately cool.

Millyard repeated the process with the cam covers, creating one to cover all six cylinders. The tricky bit was that these cam covers are magnesium, which is extremely flammable and difficult to extinguish, as he demonstrates (stopping for a cupcake on the way, of course). He cut strips of magnesium out of leftover parts to use as a filler wire, ensuring that the filler would be exactly the same material he was welding on the extended cam cover.


All of the pistons were good, so Millyard chose the six best to go into his engine. All 24 valves were in great shape. He only had five good cylinder liners, though, since one of the original engines had rusted inside. In true Millyard fashion, he simply fabricated his own. Speaking of fabrication, Millyard converted the Yamaha’s original wet clutch to a dry clutch, as on the Honda RC174. He created or heavily modified all the parts to do this, along with a new oil filler. Millyard even made a stainless steel toe cover to prevent him from getting sucked into the completely exposed clutch.

One video in the series shows Millyard extending the crankshaft and crankcase to match the heads and putting the whole engine together. As before, he does an excellent job explaining every detail of his design and build process in terms that a layman can understand, keeping no secrets about how he did it. He calls this the RC374 both as an homage to Honda’s original model name, as well as a more accurate description of its displacement.

I am completely blown away with any of Allens creations and the ease of how he actually creates a unique part, such a laid back fella with so many skills that it would take a year just to get a sample of what Allen has accomplished in his shed/garage back home.

This is Christmas and I am sure you lot are off of work and I am also pretty certain its bloody cold where you are right now?

So, what better way than to watch this at home on the big screen if you can? Only 15 minute videos but if you are into engineering and want to see a Pure Genius at work, you will be mesmerized at the skill set and the ease at how Allen accomplishes any task at hand.  he would make a great Professor at a university to teach you engineering that’s for sure.

The sound of this screaming 6 cylinder Race bike is the same as the Original as I have heard it, I love everything Allen does with all his machines but these Videos are all of building this RC347 Honda Six. so take a hour or so Break away from your Turkey, Ham or tri Tip and sit and watch how this Mechanical Wizard creates this unbelievable machine.

 

Merry Christmas from Carpys Cafe Racers.

Some older machines I built

Funny thing the internet, although it may seem new, it has been around just over 20 years now and I remember when we had My Space etc, the things we did to promote ourselves back then.

Anyway, just thought I would add this old video, forgive the clarity, but I created some cool rides back in my garage and thought that I would share with you all today.

 

My shipping adjuster on the website took a massive crap and we have just about sorted it out and also added a choice of UPS as a service for way cheaper shipping too, thanks for ordering from me at this time of year, I really appreciate it.

Here’s that Old Video of just some of the bikes I used to create at home.

 

15 days until the Jolly Round Fella Scrambles down the Chimney

Well, just over 2 weeks until the big day, I am sure many of you have only just thought about presents and the like and a mad rush trying to find stuff in the shops or on line?

I love this time of year and right now I have been shipping out many Exhaust systems to people all over the globe and even have a festive $100 off exhausts to try and give some Christmas cheer to you 2 wheeled racers out there. I am going to try and make some new parts in the 2023 season and am quite excited about that, I enjoy producing something that not only fits easily, but has a great look and works very well, also keeping the product affordable.

 

If I can help from Tee shirts to handle bars, or Seats to hoops, drop me a line  carpy@carapyscaferacers.com or drop me a Dime or Text at 714-598-8392 as I am always happy to chat and have done for almost 23 years here in Southern California.

Thank you for supporting me, I am still a one man band and love it that way.

Getting closer to Spiral Ham time

Jeez, time is flying by and I have many projects to get wrenching on, bikes to build and engines to strip but I do make fun Gift idea’s like Mechanical Lamps and also I am coning with new affordable parts for your machines, so be sure to check the website regularly as there may be some stuff that appeals to you.

From seats to handle bars, from Mirrors to signals, I hope to try and offer a bigger variety of products to help you get on the road, I mean, I am now coming up to 23 years doing this and never do tire of making parts available and, at a affordable price.

I hope to make more Gauge faces , so you can change out your faded, cracked or boring stock faces, I first did this about 35 years ago, nobody was making anything like this, so keep ya eyes peeled for cool sets.

I am always here to help, if you cant find something, Call, email or even text me on 714-598-8392 and I will do my best to get you covered, its what I do.

 

 

Happy Thanksgiving Everyone

Well, its that time of the year already, I will not be working at all in the Barn, its nice to celebrate Turkey day and I will make sure I shall to its fullest. Burp!

Hope you are celebrating too if you are in America that is, and so tomorrow, work will be flat out as the festive season will then be upon us.

Just wanted to take this time to wish you all a Very Happy Thanksgiving and than you all for your orders, I love my job and what I do, this Thanksgiving I sit, eat and feel thankful for all that this wonderful country lets me be a part of.

 

Rebuilding Old Set of CB750K forks 1974 HONDA

For many years I have rebuilt my own forks, and the transformation is so abundant, I wanted to share what I do in the Barn with you lot and maybe you can have a go at resurrecting your own set?

These tired front forks came off a 1974 CB750 K and Customer wanted Rebuilt and Polished suspension, so this is what I did to these old girls you see here.

The Lowers needed to be stripped apart and then sanded and cleaned then I will polish them to a Chrome finish for that Custom look, lucky Honda cast these quite thick so plenty of meat to polish by hand.

The upper tubes are toast, this is a common issue with the forks as originally Honda fitted fork covers and the  condensation in different heat simply left water droplets sit here and slowly rust the chrome away and into the tubing, you would not notice at all until you took the fork ears off the bike.

I have taken these apart and bought replacement Chrome tubes, then I sanded and buffed the lowers to a mirror finish, I covered in cling wrap to keep clean whilst I assemble these so as to not scratch the surface.

I slid the dampner into the fork tube and then inserted the upper tube into the lower stanchion, this is secure by a Bolt with a Copper washer right under the fork leg, secured with allen wrench and began the rest of the rebuild of these forks.

I have fitted so many of these Fork seals over the years and people always ask me, which way up do you fit these, I tell everybody that when you fit Honda seals, the ID Numbers should be facing you when you look at the seal seated in the fork lower.

Also, many people ask me how I fit my seals into forks, I have seen people use scary tools or hit with a screw driver, usually ending up tearing or making a hole in the seal, so what I have always used is a piece of PVC that I bought 20 years ago from Home Depot, this is the perfect size to insert oil seals .

I simply slide the PVC tubing down the fork leg until it sits on the seal, it fits perfectly and will not bind up as this makes sure that it is level when you tap the seal into the fork leg.

Personally, I use a Rubber Mallet and tap the tubing until I feel the seal bottom out on the inner shelf the fork has and then I know she is all the way home as you will feel the resistance right away and you can see the recess in the fork where the snap ring goes.

Some Honda’s have these snap rings, or as we call them in England ( Circlip ). But some early models had a spring clamp, but this is a snap ring that sits in the bottom of the cup of lower fork and secures the seal into the stanchion.

I use a set of Circlip Pliers but long nose pliers will do as you need to squeeze these together to slip into fork lower then release to lock seal in place.

I then slide the New Dust cap that I sell many off from the website, over the tube and down to the lower, it simply pushes on and sits tightly over the end of the fork and dresses it well.

 

There you go, nice and snug over the lower fork and easy to fit to be honest, and this job can be done pretty much by anyone with minimal tools.

I used New Stainless Lock Washers and Stainless Flange nuts for the bottom cups to finish them off nicely and its ready for Fork oil which is 5 ounces, I use Automatic Transmission fluid, always have and I throw in a couple of stainless washers on top of the spring to set the preload that I like.

And there you go, ready for the customer to fit back onto his Motorcycle and have fun on the tarmac, just thought I would do a little blog on what I do from time to time as many ask me for tips etc, thanks for watching.

The transformation is so cool to see, I often stop and look at what I have accomplished and you will do the same thing for sure.

So have a go at your ones, you may surprise yourself and save some money at the end of the day too.

Any info you may need about anything bike related, email me on carpy@carpyscaferacers.com or text me on 714-598-8392 I am here to help.

 

 

Thanksgiving Special on Exhausts, $100 OFF

Well, to celebrate Thanksgiving I thought that I would help you all out by reducing the Exhaust Price by $100. how cool is that?

Thank you all for supporting me, I value each and every one of you, these exhausts Perform and sound bloody awesome, making these over 20 years now and ship all around the globe.

 

Working on Projects in the Barn

Time does not stand still and I now have all sorts of work to do but glad that I still get many emails, Phone Calls and of course texts, asking about builds, parts, service or idea’s etc, I love what I do and even though I really have had not had the time to build cabinets and work benches , I have enough to get by and get a few projects sorted out.

A lot to do and still get some what organized in the Barn, I will move my Model A Roadster out and start to get myself in work mode as quite a few things I have to do in here and its sure nice after 22 years doing this, I am still popular with the Public all across the globe.

You may remember The Red Devil I created about 2006, it got in a wreck when we were out riding about 13 years ago, and now it is time to fully rebuild this Old Caff Machine that has done many miles over the years and to resurrect this to a Tarmac eating two wheeled Monster will be a challenge but I am up for it.

This will be a frame off build and will be taking the old girl completely apart and will remove the paint from the frame and powder coat a Gloss Black, but keep the rims RED as its a great offset for this bike and nobody was really doing it when I did this back in the day.  I’m keep the tank but need to repair it as it has some damage from the crash, there must of been 100 Yards of Oil on the road when she slid on her left side when a Pick Up truck slammed into it on a off ramp from the freeway right in front of me.  Poor lad had a bad leg for a long time but now, years later, he is looking forward to a revamped Red Devil Motorcycle.

But I am looking forward to turning a few wrenches and creating some unique rides, the RED Devil will take some time But I have the Super Sport to finish next and then once I am happy with that, I shall offer it up for sale.

The Milwaukie Special will get a Full RED and White Paint job and will be quite the head turner, with great 4 into 2 exhausts and a fully rebuilt motor, this will scoot along quite happily, anywhere around the USA, as its had tons of work done, from the painted frame to the hand drilled rotors, this is quite a work of art that I really enjoyed creating.

All sorts of motorcycles in the shop now and of course the Mint 550 Supersport is always a lovely sight for sore eyes, as well as the 883 Sportster I am building too that will eventually buzz around here on the twisting roads that we are lucky to have we we live.

A Lot of 750 Bikes too in the stable with more to come, I hope to be creating a few cool rides and then offer them up for sale, I love building Motorcycles and am quite happy when I get to use my creative juices and try and build something interesting.

It will be a busy year here at the workshop and looking forward to building these and making some interesting inline four Custom bikes for people to really have fun with.

This old Girl is an old Drag bike that was built in the mid 1970’s, but may be transplanting it into the RED Devil if the Mill is OK as have no idea if she will run, but this is no ordinary engine, this is a RC COBRA Engine, with extended Cam towers and an RC Engineering Exhaust, along with an ARD Magneto and a set of smooth Bore Mikunis.  So before I get too crazy in stripping this old bike, I will need to get her going, this is a long term build but I hope I can get her to run again.
