hi guys need some advice, im rebuilding my 30cc engine, it has 30mm crankshaft, i want to make it 27.2cc by a zenoah head 34mm and piston, what size of head gasket i will use? And what size squish clearance i must look?


Thanks guys
 
i have not used that combo , and would prolly do a squish on it to see and measure.

.040 would be first guess, definitely would be a revy unit.

seems like there are some other mods on boss tabs but not sure.

thats a 280 case and 30mm rod, right?

True, Just saw on other forum that 27.2cc will give more torque and rev, maybe it will just applicable to a modded head.

no its a 260 34mm with 30mm rod, just not sure if it will be ok on non modded head
