so im starting to build a 49 cc engine. i bought a 49cc mini bike engine off of ebay with bent cooling fins for a mock up for 70 bucks.
I looked at the piston and it has tow excessively large piston rings .075 x2 piston rings so i found an chain saw piston that has one .056 piston ring that will create less drag hopefully equaling more RPMs. the chain saw piston is approximately .035 taller so i will account for that in my model. here is a picture of the case design so far.
Still have a long way to go but any advice is greatly appreciated thank you
