im looking for what the compresseion and squish should be with both the thin and thick base gasket on the 600 twin i am at 500ft sea level. i measured he squish it was somewhere around .120 i do not know if that is high or low on a sled but in most of my 2 stroke atvs i run a squish of about .030. the reason i am asking is i have my turbo all sealed up and ready to go im am extremly worried about detonating.
