79 KZ650B OK Basically I love this bike and want to big bore it. I have questions for anyone who can help.

I know I can usea Piston kit to get 700cc.

Can I fit 750 Cylinders on a 79 KZ 650 if I bore the case to fit the sleeves, then bore the cyls for the 810cc kit? If so which donor cyls should I be looking for (IE: Spectre, KZ, LTD, GPZ)?

Will a 82 GPZ cam fit in the head, and does anyone have a set they want to part with?

Or barring that does anyone have a KZ 750 GPZ 750 and can give me the dimensions of the head bolt spacing (L side to R side).

 

the most simple way is the way i am doing.. to find 1980 kz750 jugs that have the notches for the old style timing chain that way you can just get your 810 kit and a 750 head and your ready to go.. the new style chain requirs a different crank... also its said that milling the heads .020 and dialing the cams is the best way to make some real gains...
