    88 650sx motor swap?

    Hi I don't know if this has been posted elsewhere but I have a 88 Kawasaki 650sx that has the following mods PJS race head, PJS exhaust manifold, PJS full exhaust, PJS intake manifold and a mikuni 40sbn carb. I was wondering if I could swap out the block to a 750cc motor from a 750ss. And if so can i still use the exhaust system and the intake system? or do I have to switch over to all of it to 750sx parts. And does the same go for the electrical system?

    It is a common swap but I'm not sure about the year to year stuff. has multiple build threads on 650/750 swap.

    Thanks for the info I checked it out and it said that I could use the same electrical system but I have to use all of it I couldn't piece 750 and 650 parts together. But i did not really see any information on the whole pipe and intake questions. If anybody out there knows I would greatly appreciate feedback
