My CB750 Drag/Cafe Project Bike Thread
I'll be using this thread as a way to document my legalization of the most recent acquisition of my motorcycle collection. I'm in my early 20's so everything is being done on a budget with this one. I've acquired boxes of random spares with this bike, and have already begun buying the necesary electrical goodies. Ok, so here it goes:
Frame: 1978 CB750K
Engine: 1968 CB750(not sure which letter)
This was the last incarnation of a drag bike raced by my previous service manager at my last motorcycle shop. He had a couple of these but this was his fastest. As it stands today, it is a gutted out CB with 1250cc motor and high comp pistons. Needless to say, I've already sprained my ankle kickstarting the thing! It was stripped down and built up from scratch to be as fast as he could make it. Aftermarket swingarm, no rear shocks, he even gave me the wheelie bar. There is no battery, no wiring harness, no lights, only an ARD Magneto firing the plugs; and a kickstart to sprain your ankle on.
The exhaust system was custom made for the bike in 1979 and is a 4 individual pipe megaphone system with ZERO baffling, pure straight pipe (hurts your neighbor's ears at idle.)
The carbs are aftermarket Smoothbores that Dave (previous owner) took great pride in.
The bike basically sat covered up in the shop for 25 years. It has NO corrosion, the paint is mint, and the thing fired up in one hour of fiddling.
Yes, it is a race bike, it even still has the slick on the back.
Make it street legal! I have 2 major plans in mind. Plan A involves a complete teardown to the frame, painting everything White/Black/Red and putting a cafe fairing and rear shocks on it. Plan B involves leaving it vintage style and just cleaning it up real nice and maybe even leave the solid mount rear.
Both plans require lights to be added on. This bike had the stator and flywheel removed as well as the entire harness and battery, and I've already purchased a stator, flywheel, regulator, rectifier etc.. and the other electrical parts I am pulling off of a CB1100 parts bike that I acquired at the same time. I will leave the ARD magneto and install a very small battery that will only power the lights. I've never made my own wiring harness before so that should prove to be pretty interesting. I went to college (3/4 finished) for electrical engineering so I have a decent idea of what I'm doing. Any tips are always welcome for creating this harness though!
So..... I will keep this thread as a place to post up fresh pictures of my progress and to hopefully get some help if need be. Anyone else on here absolutely love these things??
Also, what's a good way to NOT sprain your ankle kickstarting something like this?? I can't afford to be on crutches every other month!
Oh, right... Did I mention I got the bike for free?
