just checked the pistons i have & the 86 rm & 87,88-92 (wiseco)have the same dome also checked factory suzuki rm piston & they are the same but the 87 is a newer prolite & the 86 rm used a flat gasket the pins are the same length & dia but the prolite pins are tapered & lighter
how do you post pic on here & i'll post a couple of the pistons & the cut away
i'll try to describe it if you put the piston in the cyl with the top at the bottom of the ports on the intake side the cut away follows the arch in the sleeve on the intake side
btw is that a new 86 rm cyl ? those are getting hard to find
also if you have an rm base gasket they are metal not paper & solve 1 of the problems on the 87-92 lt's leaking/blowing base gaskets if not cometic can cut you a rubber coated alu one |
