Honda cb750K 1976 Gets a work over

Well, the weather is now Hot as the inside of Gandhi’s Boxers, but I have been doing some work on the K6 Honda, I started to clean a few bits up as she had sat for many years in a back yard.  So I thought I would clean her up more before selling this inline four machine.

The bike had low miles but obviously the condition had deteriorated due to being sat out in California weather for many many years, but the more I cleaned up, the more I put into this 500 pound of Japanese machinery.

I removed the rear wheel and swingarm as the swingarm was in need of having the paint stripped off of it and then have it powder coated, so I just got it back from the coating company I use and fitted it right away, I had to drum sand where the shock bushings go and fitted new Genuine Honda steel Bushings. You can see the rusty main stand in the picture, Once I have this back on the floor, I shall remove it and powder coat that Black too.

So much to do, the wheel is all rebuilt and I polished the hub and fitted new bearings etc, new spokes and new tire, I fitted the Cush drives this afternoon and its now ready for the brake hub to be fitted as it was in a sorry state too.

As you can see from the photo, she is all there but I stripped it and polished the outer carrier and fitted new shoes and actuator etc as I want this to look nice, not restored from frame up, as I don’t have time and space right now, but just a nice looking K6.

As you can see, this is now taking shape, I wanted a fresh clean look on the rear end and I believe I shall achieve that with a few more hours work on this classic inline four bike

The safety guard for the rear sprocket has seen better days and as you cannot find nice ones anymore, I had to get the hammer out and clean the dents up from where the chain has caught etc, these always get abused but wanted to make sure I got this as nice as I could and then send it off to the chrome shop.

A really nice job and am more than happy with the finish as this was pretty torn up when I removed it from the rear wheel, so not time to start bolting it all back together.

You can see I took my time and also used Genuine Honda parts where ever I could, the Bushings for the shocks are factory ones and I also used a New rear brake rod as the old one was really bent up and rusty to repair, I also purchased new chain adjusters to clean the rear end up and set the wheel off.

It is coming together and took my time as it was so hot today and of course I was on my own and do not want to scratch anything, but as you can see this bike is looking nice, and even though not a show winning restoration, it will be all there and I shall be fitting brand new 4 into 4 exhausts to give it the factory look it had when it left the factory all them years ago,.

I chromed the rear brake Stabilizer bar as that was rusty and new hardware through out, looking so much better than when I dragged it home, fitted New shocks and put the new chain on and set the tension right.

It is missing the chain guard and hope to purchase a New one soon to finish that area off right but I am sure I can get on with many more things before I need to attach that part.

I did buy a repro rear guard as mine had rust on it, but, it was so far out of wack I bit the bullet and paid a few hundred dollars to chrome the original rear fender and sent the copy one back in disgust. I prefer Original parts anyway and the list goes on of what I am refurbishing to get this bike right.

I fitted the original back into the frame and a new Old stock inner fender to clean the underside up. I have chromed the rear light assembly and that is going on right now.

To keep with the clean look I splashed out on a New seat for this K6 and glad I did to be honest as the original had seen better days, this really is a good seat and fits super well.

I put the light assembly together, using New light and chroming bracket, this is now all together and will wire tomorrow as its getting late but thought I would share with you today to show you how I am getting on.

Happy 4th Of July everyone

I love having this day off, gives me time to reflect how lucky I am to live in such a great country, I have always loved living here and especially here in Southern California where the weather stays pretty constant and ideal for taking your motorcycle out and about.

I have much to catch up on and as my girl is heading back from the East coast, it will give me some time to try and sort the workshop out a little as I have way too many bikes in there that need attention, I dragged a few out of gardens and the K6 that I am working on never ran since the 80’s. I was just going to see if there was a chance I could get it running, but it has turned into a project that I should of left alone. But you know how that goes, when you think to yourself that you will just clean this up, change that etc, well I have done so much I should of ripped it down the frame and started fresh. But it should look nice when done and out of the way to give me a little room to start on another one.

The rear wheel I just could not clean up, due to the rust that had accumulated from sitting in a back yard with sprinklers that went off twice a day for years, so I had to pull the rim apart and located a new old stock 18 inch rear rim and purchased new spokes. Polished the hub and fitted new bearings.

Next up was the beaten up rear sprocket carrier, its seen better days but do not have a spare, I have a 78 one but the offset is different, so I will try and clean this up as best I can using my little buffer wheel and some compound, but it wont be too show polish as I am getting too pernickety with this and really just need to get it running well and of course riding well.

As you can see, the poor sprocket carrier has seen better days, bearing is fine and will repack with grease but need to clean it up a little before I attach that to the hub and then the sprocket as well as the Guard, but that is at the chrome shop as I am waiting on that.

Still a little more to do before I am happy with it but at least this is getting back together and I am now waiting on the rear swing arm I took out as I have sent that off to get powder coated as that too was rusty and needed attention from sitting for so many years. But will keep you updated as and when I work on this old girl, it will be fun to ride with all new parts and will be dead stock, I now have Brand New 4 into 4 exhausts for it that I purchased in Japan, so this will look pretty cool once done. I will ride it a little then offer it up for sale.

Have a great day and hope you enjoy what ever you are up to in the world, I thank you for all your orders too and if I can help just drop me a line. carpy@carpyscaferacers.com

 

 

 

 

Refurbishing the 1976 CB750K Honda Four

Posted on by Steve Carpenter
05 Jun

Here we are with another episode of tweaking that old 1976 CB750K Model Honda, she has been sat for so many years, I was initially just going to get her running and sell her, but I have grown attached to this machine and its my best year personally, so thought I would remove worn out parts and fit brand new ones. Still a ways to go and I shall blog as I go along but – Eventually this will start to look like it did when it came out from the factory. Except the paint as that’s a really expensive process these days but I may even have a go at that later who knows, so stay tuned….

I didnt like the patina on the footpegs, even though this particular machine only has 17,000 Original miles on her, she has sat many decades in a Back yard and the eliments have taken a toll on any of the parts and brightwork, you can actually see that the foot peg rubber has no wear at all, which is more validation of the low milage, but I wanted to fit some OEM parts and here is a set of New pegs that I will fit to the bike.

The same thing goes for the rear brake, it had heavy rust pits that even I could not be able to polish out, so I thought I would buy an OEM genuine Honda one and that will help clean up that area that does get neglected over the years on these machines.  Not cheap but rechroming would of been even more expensive, so this was the lesser of two evils.

 

The Original Kick starter also has pitting, so I managed to track down an original New Old Stock one and later on I shall probably get the original one stripped and chromed again but not right now.

The Honda should start to look like it originally did when it rolled out the door all them years ago and I am enjoying the time and effort to get this to where it really needs to be.

I removed the old clutch lever and thought I may as well address that issue with a New version and that will clean up the handlebar area somewhat as many people leave that part of the bike and I always notice that.

Now that looks a million times better and with NOS grips too I am more than happy to get on with another part of the bike now, I am in no rush at all with this k6 and when completed will offer it up for sale.

The poor headstock always gets left out, the steering stem nut and washer was begging to be replaced as well as the steering pinch bolt, I could not leave the bike with these parts like that.

I try to use as much Genuine Honda stuff as I can lay my hands on and this is the case right here, it is fantastic quality and you know not only will it fit, it will last many years too.

So, another job done and if I find anything I feel that needs sorting out I shall of course do it as I am on a roll now, although this is by means no restoration, just a revamp of tired parts.

The starter motor covers always rust as they are easily open to the elements, so I ordered a new one as this has seen better days, what do you think?

A big improvement and I could go on forever on the bike, just a few of the fundamentals needed to be addressed but I still need to rebuild a rear wheel as the original one is just too rusty to strip and re-use as its too dangerous to mess with stuff like that.  Next up is to fit the footpegs, a New old stock brake pedal and kickstarter to at least clean that side of the bike up and look more original now.

Looking very much like the bike it was originally at the factory and am pleased I went this route on this one, although still many more things I have to replace to get it to the standard I will be happy with, but each week that goes by I give this a nod of approval.

So, I will be working on removing the center stand and painting it as its looking a little weather beaten, its a big heavy part but I want to get that looking good, I may Powder coat it for long lasting life in all honesty, so stay tuned……
