So i found both 600 and 750 engines for my 97 GSX-R 600. I figured if im gonna buy a new like to pop a 750 in there. Before i go and buy the engine..i wanna know if it can be done. I know it bolts right in, but are the carbs and airbox and plugs all the same? or am i gonna have to buy a new set of carbs etc?? Also what about the size of the gas tank? same size? I know the rev limiter will be diff since the 600's rev higher than the 750's. if anyone knows for SURE if it can be done...please post up.or PM me..cuz if its possible...jus droppint he engine and hookin everything up, im gonna go ahead and pick up the 750 engine. Thanx guys.
