what a pain!

A ZX11 lower end uses the same crank, rods, pistons and cylinder as our GPZ. 
However, the cylinder head and cams are different. I was suggesting using a 
ZX11 "short block" and bolting your GPZ cylinder head and cams onto it. They 
will bolt onto a ZX11 engine no problem. I just don't know if the engine 
cases (that have the mounting points) or if the countershaft sprocket offset 
is the same as ours. If it were me and I was truly interested in keeping the 
bike, it's something I would look into.
