Topic: Bluenose CB750F build

[rangerdave1]

I have been lurking the forum for a few years on and off and have finally decided to make the plunge and start my project. I bought a 76 CB750F over 7 years ago. The bike had last been registered in the mid 90s and the previous owner had made some sort of attempt to make in to a café, or I think that was the intention at least. For the past 7 years, It sat in the shed covered while I collected parts and tackled other priorities. The bike was partially disassembled when I got it but was still somewhat of a roller. The engine was not seized and I kept oil in the cylinders. While it waited patiently, I built a 79 Suzuki GS1000.

In the month of September, I decided to start the restoration with the intentions to build a café ish racer while trying to keep a somewhat period correct look. I decided I wanted to open up the triangle so that meant removing the stock oil tank and moving the electronics. I want this to be a quality build so the engine is coming out, frame sand blasted, and every nut and bolt will be reconditioned or replaced along with all the other parts . I have a Yamaha FZ1 as my modern bike, a 79 GS1000 (bored to 1085) with modern bits and now this CB750f. I considered putting a inverted fork on this one however I did that to my GS1000 so I decided to keep standard forks on it.

As of right now, here are a few of my parts:

-Air tech fiberglass tail section
-GL1000 front end
-2.5" gauges
-Moto GPwerks Stainless exhaust (Yoshi style)
-Clubman bars (likely to be changed to Domino clip-ons)
-Cognito Rearset brackets (GSX-R master cylinder)
-Dimecity rearsets (likely to be changed to something more classic)
-New shocks
-bearings, bushings through out
-836cc kit, CX1 cam
-Custom oil tank (Roepke) by Curt @ Anything Goes Custom Cycles
-Underseat electronics tray
-Antigravity battery (to be mounted under the tail)

Here are a few photos of what I started with. More to follow as progress moves forward.

I started cutting the tabs and rear pegs that will no longer be needed

Changed the front end to a 76 GL1000 fork and brakes.

Added the steel Cognito rearsets brackets which will required some modifications especially to the pivot bolt as it is not long enough right now. I installed the Dimecity rearsets I bought however I find they are little to modern and will be looking for some that are not so CNC'd (if that is a term). Basically I find CNC parts are wonderful however a little out of place on this build so I'd rather have rearsets that are a bit more 70's looking. I like the look of the Slipstream cycle rearsets like the ones I have shown here. The Cognito brackets are made to take GSX-R rear master cylinder which will simplify and clean up that area od the bike.

Dave,

I did the GL front swap on my 750.  I think it's a good period upgrade.  You will want to get new springs since the GL bike is much heavier.  You should consult with Race Tech and they can sell you the correct springs based on the new weight of the bike.  Ask for Matt Wiley.  You might want to incorporate their gold valve emulators, too.

Thanks for the advice. I will look in to that once i get past the fabrication stage.

Since my last update, i have taken delivery of a GSX-R master cylinder and started fitting it to the rearset bracket. I still have some work to do as the clevis not match up but since i have other rearsets on the way, i will wait and see how they fit first.

 I was able to get my hands on a longer pivot bolt which needed longer threads and also need the threads on the engine bolt to be lenghtened as well. They are both at the machine shop right now and hopefully will be done in a few days.

I also started mounting the oil tank to the frame. I used the original rubber gromets from the honda tank on the custom tank in hopes that it help dampen some vibration. I made some small bungs that i shaped to the frame rail and put a few tacks to hold tem in place for now.


On to family duties now, more work to come in the week or so.

Just a quick update.

 I found a longer pivot bolt but it needed longer thread so off it went to the machine shop along with the lower engine bolt which also needed longer threads cut as the original foot peg mounts where much thicker. Using a washer between the new bracket and frame, it spaced everything the right amount.

The original kickstand was a bit of an eyesore so While i had the brackets off, i also cut the kickstand off and will be installing a much sleaker kickstand which i got from Cognito.

The new rearsets arrived from slipstream which i find fit the look of this bike a lot better.

Now i need to cut the pivot bolt and engine bolt to length and install the shift linkage.

Stay tuned for more updates
