After talking to a guy in Canada about the KZ750 twin he races I have decided to build an all out track/race version of my own. I have been slowly accumulating parts for the engine and recently picked up a complete chassis for the build. Its the roughest bike I have ever bought. Literally everything, except the frame and the engine cases, will be sold or junked.For $100 with a title I don't think I can go wrong.

I have never done any road racing. I've done a couple track days and loved it but it is expensive and hard to get out there. Right now the plan is to build a track bike that will see the street once in a blue moon. In reality this project will mostly be an excuse for me to make cool shit and make poor financial decisions. That being said; most of the modifications I plan on doing should be legal for WERA Vintage 5/6 should I choose to race down the road. Goal is 80-85HP to the wheel and around 375-390 lbs.

This thread will proceed rather slowly at first, but I'm starting it now so I can document things as they happen rather than trying to dig up photos and info down the road. Stay tuned for vigorous turd polishing.

Right on !. You weren't kidding. That thing is/was rough. I'm in to learn the build info you've found.

I call them "fence row rescues", because that's where I found them. A little bit, maybe just find a bolt, each day and you will surprise yourself with the progress.

Because knew I was junking so much I literally just cut off the whole sub frame without dissembling. The black stuff on the ground in the picture of the frame all came out of the subframe, full of rust. lol. luckily I dont think the structure has been compromised by rust.
