I am trying to find piston rings for my 06 Busa. My Manual says my cylinder bore is 81 mm however I seem to see a lot of piston ring sets that are 83 mm and it seems to by hard to find 81 mm ring sets. So my question is, and I hate to even ask this, but does 83 mm pistol rings go into my a 81 mm bore cylinders? I do a lot of car work and have rebuilt a car engine and this does not make sense to me.
