Hey everyone, I just bought a 77 CB750K. The bike is in pretty good shape, needs some paint, a carb rebuild, other maintenance. Anyways, I'm just starting to tear into it, and I have some questions.
1) I took the tank off, and there is a little nipple that comes out of the bottom of the tank, towards the middle. It didnt appear to be hooked up to anything. Is this just a breather that I can run to the bottom of the bike, or does it go to something specific?
2) The throttle is obviously a pull-pull setup, and someone converted it to push-pull (i.e. only the front cable is hooked up), was this a common mod back in the day, or could something more be wrong with it?
3) Are there still parts availiable to rebuild the caliper on this bike? It appears to be frozen. The master cylinder looks good yet though.
Also, I came across some Remus exhaust pipes off a Ducati Monster. Since this bike has no exhaust, I figured I could pick up a couple of 2-into-1 drag pipes, and cut and weld them to the Duc pipes. Anyone have much experience with mating modern sportbike pipes to our old headers?
Here is a picture of what I'm dealing with, including the Duc pipes mocked up to it.
