Boring your engine

Ok....Where do I go, to get oversized pistons, crank and everything else needed to bore out my engine..?

 

Does anyone know?

 

You might be able to get a set of piston that are oversized but you will more than likely have to have them specifically made. Most of the major upper end companys can make a custom set of pistons, Viola, for example. I do not think it would be worth the money to have them made though. Would more than likely run you more for the pistons than purchasing a good used motor.
Might want to check in on having your head shaved if you are looking for a little bit extra. this would decrease you combustion chamber volume thus increasing your compression ratio. In essence a poor mans bore. Remember thought that this does increase combustion pressures and can cause alternative problems if other details are not paid attention to.

 

I know cheapcycleparts.com lists them available for the 650s. Stock, 1st and 3rd oversize if I recall correctly.

 

why would you need a crank for a bore job?

 

750 Seca's use the same pistons, etc. as a XJ750 Maxim (1983)......see this thread:
