bought a 99 gsx rfi and the guy told me it needed a tune up. (my fist pwc) well needless to say it was running in one cylinder the rear one had been blown for a long time. i found a place that will bore and hone and match new pistons and rings and gasket kit for 300.00. my qusetion is it says if you bore over .010 you need to relieve the RAVE valve. they say with a sander or grinder. is it ok to do this? doesnt sound very percise
