4FU vs Athena 170



  • 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.



  • Yeah 4FU barrels are plated. So are the Athena barrels IIRC.

    It's about £130 to have it replated. PJME will probably drop a liner in there if you wanted them to.
