Before I begin I want to give a huge shout out to Kenny over at Cycle X and the one and only Mrieck here on the forum for all the help and guidance they've given me. I think Ilja's cb750 and Bill's Purple rain builds deserve their mentions as well for planting the seed in my head for a boosted build. Also a big thanks to Bill Benton, 754, Medyo Bastos, and eli for sourcing countless parts for the build you all have been a huge help in making this possible.
The engine aspect of the build can be found in the high performance section under "Turbo Billet Block CB750" I figured it was best to start a new thread entirely in this section of the forum for the chassis aspect of the build. I had previously made a thread about the build but it was too wordy so I hope this thread can be more easily digested. This bike was a genuine racer back in its day but was crashed and left to rot in a back yard before I found it. Previous RC 850cc engine was destroyed when crashed in the early 80's.
The Frame of this bike is a K1 so all the supersport parts were modified to fit.
There are little to no photos of the bike 3 years ago when I first got it but many of the vintage race parts that are on the bike now were on the bike then such as:
-Dresda swingarm
-Krober tachometer
-Wheel set (Goldwing front hub and 750f rear hub both laced to DID aluminum rims)
-Brake set (750f rear and cast iron twin disk up front)
-Futura headlight mounts now flipped upside down to look modern
-Home made aluminum rearsets
-Worked fork set by Forking by Frank
-Vintage aftermarket twin front brakes and rear sproket
-That #$%*in seat (Brand unknown)
All the parts you see have been thoroughly cleaned and rebuilt this past year but overall the chassis work has been a bit neglected. Since the engines been on hold at Mikes shop the chassis has been the only thing I've been working on.
I have a new supersport tank on the way as this one was on it's last leg the last time I redid it so I guess my brother knocking the bike off my lift was a gift and a curse. An aftermarket petcock and modified tank breather are going to be addressed the moment the new tank arrives. Again shout out to Medyo Bastos here on the forum for always hooking it up when I'm in need.
The bike had no side covers when I first picked it up so I didn't know how bad it would look with standard F1 covers on it. I decided to cut the rear of the cover to match the lines of the frame. I plan to get a cover for the oil tank and do the same thing as much as I hate covering the AAMRR sticker
The seat doesn't currently sit flat on the frame as the sides of the seat hit on the rear shocks. I'm going to make a custom wood insert under the seat just to raise it 1/4 inch an make everything sit flush. The seat will also be cut in the front to match the angle of the tank so it sits flush in that regard too.
Finding a place for the rear taillight that also fits the theme of the bike has been a challenge for sure i'm gonna attempt to mount an LED strip under the seat which will look sleek and badass at night.
All new brake pads and stainless brake lines are in the near future as well. I'm going to ditch the original brake light switch and run both the lines from the calipers right to the master cylinder for maximum response. the master cylinders and calipers will all be rebuilt and polished to fit the scheme of the bike as well.
The steering damper was made out of two I had laying around. I couldn't find one that would work right for under 300$ so I had to improvise and I think it came out alright.
A very large oil cooler is going to see itself onto the bike . Whats the biggest unit ever fit on one of these frames? I've been looking at some 11 x 7 x 2 inch coolers utilizing 8AN lines but I don't want it too look too preposterous. The battery area will be sectioned off with sheet metal so the heat from the turbo doesn't see itself into that area. I'm thinking a Water-Meth tank will sit where the old electronics used to sit, hopefully a 1 gallon tank? Once I finish up with some more mods everything that looks less than perfect will be powder coated. I'm thinking of leaving the seat with the original paint but may have it redone exactly the way it is.
