KZ750B2 vs. KZ750 Twin CSR LTD Engine Differences

Hey,

I've got a 1977 KZ750B2 Twin and was wondering if a KZ750 CSR Twin LTD model piston and rings will fit.

It seems like there are no internal engine differences. It has the same 78X78mm bore and stroke.

Anyone know if it'll fit?

Thanks so much!

Ya they use basically the same everything for internals. the only thing that you should worry about is that the engine has a different cam in it that would make the valves kiss the pistons without enough piston relief but as long as your current pistons look the same on top as the replacements your golden. Make sure to post pictures your project is done, I love to see what others are doing with this bike.
