Head swap?
I have a 1980 gs750 as I go through my repair manual I've noticed that I can remove the head and cylinder and leave the rest of the motor on my bike, I was wondering if anyone knows if I can use larger heads and cylinders on my 750 crank?

I think your options are to bore the cylinders oversize, or install a larger engine.Ed
To measure is to know.

You can get oversized valves in the head and use Webcam camshafts. Wiseco makes big bore kits also.
But then you'll need bigger carbs
