Just got my Polini 63cc big bore for my 87 Elite. Im tryin to put it together now. There are no markings on the rings. One fits in the groove snug, the other kinda loose. Which one on top? Does the diamond mark on the piston go on the exhaust side?
thanks

yes the arrow usually goes towards the exhaust. Another indication is the gaps of the rings are always in the back, if not the wil get hooked up in the exhaust port and cause some good damage!
hehe seen it before!
