    What pistons fit in a 400?

    Hi, the reason for the question is that GS400l pistons with the 8 valve heads are no longer supported by suzuki or anyone I've found so far.

    However I don't mind boring the cylinders out to 69mm and using half a a big bore kit for the 750 as long as the piston's are for a 16 v head. Or just using some stock 850 piston's but I don't know if they have a 16v head.

    help please

    Can't help you with what will fit, but I can tell you that no 850s had 16v heads.
