71' CB750 Golden

[zuehl666]

Finished and sold this rephased xs650 last spring.

Now I'm working on a 71' CB750. Picked it up for 400 bucks, not running.

I got it running pretty quick, the ignition wiring was half assed at best. I ended up ordering a complete new optical ignition kit from cyclexchange. Eliminates the mechanical advance, excellent.

Fast Forward a couple months....

Fiberglass tank I found on ebay.uk, meant for a Norton I believe, needless to say it obviously wasn't going to fit on the CB frame. I ended up cutting out the bottom completely and re-glassing and plumbing it entirely. Its separated out for gas up front and oil in the back.

Did the seat and tank in black base coat, gold mega flakes and cleared with a 2 part auto clear. Not done with them yet, I think im going to paint the tank strap area white.

Also got rear sets from DCC, I highly recommend these.

I ended up making some plates and welding them in the passenger peg mount. This was the most comfortable location for the sets. The shift side laid out too close to the kick stand when its in the up position, my toes were touching it. So I cut the stand off made a new plate, and welded it back on a few inches forward.

Added an oil cooler, got that mounted up as well. I'm going to run this in an unconventional way. It will be in line on the feed from the motor to the tank, in hopes to cool down the oil just a bit before it enters the tank.

So here is where im at with it as of Saturday.

I also bead blasted the motor, will have some pics of that soon.

Also smoothed out the top triple and bead blasted it.

Dude the tank and seat gold flake is a bold move, and looks tits. Great build. Going on

Haha thanks. I know it looks intense now, but when the seat padding is on and with a center stripe on the tank I think it will break it up a bit. The frame will be a dark silver.

Here's some better pictures. Frame is almost ready to be painted, welded some plates on the frame ends where i trimmed it down. Welded in a bung for the petcock, trimmed the headlight ears down about 1.5 in to make the bucket tucked in more. Still have to figure out what im doing with the wheels, I want to paint the rims and hubs black, polish the brake plate and relace with chrome spokes. Bead blasted the motor so thats ready for paint too, just waiting on some new gaskets.

Few more...

Painted the frame charcoal grey. Started polishing the shocks, haven't had time for much else recently.

I got the front end completed for the most part, I need to order some fork gators still. Cleaned up the forks, made a brace, drilled the rotor.

The pattern I made I based off an F rotor, which I didnt realize was actually about an inch smaller than the K. I was able to make it work in the end though. First I dimpled each dot on the pattern.

Then went back around without the paper on and drilled each hole out. I used a 1/4 in bit and lots of oil. Only needed one bit, just took it slow and kept it oiled.

Here's it installed and with the brace. The brace is basically just a hoop made of solid 3/8 steel bar welded to some 3/16 plates.

I intended on ordering the carpy yoshi relica exhaust, but it will sweep up right where I have my rear sets. SO, I decided to take a wack at modifying the 4-1 that came on it, it needs a lot of cleaning up but it should be cool. I cut down a reverse cone muffler I had lying around and welded it to the stock pipe right after the collecter, it looks seamless in person. Might make it kick up a little toward the end, but i'll have to wait till the motor is in to see exactly where it ends up.

Very cool! I will have to wear my shades to even look at it. 8)

By the way what did you use for the mounting point for the rear brakes?
I am talking about where the rear brake would have mounted.
What did you put on that and connect to.
I cannot see your picture very well.

Everything for the rear brake is the stock setup, all I did was cut down the brake pedal arm and flip it vertical. So the linkage just pushes that forward actuating the drum. The rear sets themselves are mounted in the passenger peg mounts, I just made some plates and welded them in.

 

[cklamer]

I was told I might have to cut down the stock brake pedal and either shave it down or cut it completely down to the mounting part and have someone weld a flat tab on it.

Problem is I don't have the brake arm here I have to drive 30 miles to where the engine is being built to fetch it. BUMMER!

What kinda of rear sets are you using? Basically I just cut it to about 1 inch above the splines and then just shaved down the front to allow room for the clevis joint and bolt. You can see what I mean in the photo. Where are you located? I think I might have an extra arm laying around.

Cleaned up and painted the swing arm and rear wheel. Eventually I want to re-spoke with new spokes and paint the rims / hubs black. Still have to get a couple things like tires, battery, and a couple other little things. Next i'll have to do some more work on the exhaust. I ran into a little issue with the shifter side linkage... Running a straight piece is a pretty hard angle, it works fine just looks a little weird. So I bent up another piece I had to contour the motor which looks better and has more foot clearance, but on downshifting it flexes a bunch and hits the frame. So I'll have to figure something out there.

I got the exhaust painted and temporarily mounted. The phillips head stud screws for the flanges were in bad shape, and generally a pain in the ass, so I ordered some allen head screws that will replace them.

 

[andycafe]

Oh now that is cool 8) Gold tins with a white accent exhaust system, hell yeah I like !

 

[legitmw]

Bold colors and I like it!

 

[midlyfcrisis]

kid at work i ride with at the track saw my project and said i should paint my exhaust white...thanks for doing it,looks really cool and the gold flake is rad

 

[zuehl666]

I got the exhaust finally mounted up with new flange screws, the allen heads are much easier to work with. Finished painting the clutch cover, and other little bits. Sealed the tank with kbs gold standard, was pretty easy to work with. Just ordered some new fork seals, gators, oil pressure gauge, so I should have all that buttoned up by the weekend.

Found this written under the clutch cover, thought that was pretty cool...

 

[zuehl666]

I didnt get all the parts I ordered in for the weekend, so I just mounted the dampener and started running the wiring. I decided to make my own harness instead of trying to save the stock one. I'll have more pics of that next weekend.

I made a bracket and welded it to the frame instead of buying a clamp on style mount, this saves a few bucks and looks more minimal. For the mounting to the lower tree I just used the stock mounting hole which happened to be threaded for the M8 1.25 bolt on the dampener.

Got the tail light mounted as well, I dont like how thick it is. I think im going to try to cut the lens down about a 1/2 inch and run two LED strips inside instead of the stock bulb. Also, I put a battery kill red keyed switch on the seat pan ( Don't worry, it clears my nuts fine).

The reg/rec will be hidden in the seat compartment, Im trying to use one i had laying around off an xs650, I think i have the wiring figured out.... we'll see. I ordered a small antigravity battery which will sit in there as well. Should have everything in this week and have the bike running soon.
