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.
