I need some expertise on this. I am reassembling my engine (1st time) and using a supposedly stock gasket kit. The o-rings included for the cylinders are about 0.008" larger in the minor diameter than the ones that came on the bike when it was new (0.078 vs 0.086"). The o-rings do not fit down into the grooves like the originals and when it is reassembled, the cylinder kind of "floats" on the crankcase; not fully seating on the crankcase. I'm not sure if I should just go ahead and torque it down or put the old o-rings back in for a better fit but questionable seal.
