Hey guys! I bought a 4FU cylinder but to my surprise it needs replating and it has huge sieze on the exhaust port that i didn't see as it was covered in grease..
It will cost about to the same to fully get this cylinder running as a Athena 170 kit and i can always return the cylinder to the guy who sold it to me. I have ported lot's of 50->100CC engines but never done anything bigger. Im building this engine for daily use, wheelies(need torque) and some race pulls with friends from time to time.
