Hi!
I'm from Romania and right now i try to build same kind of engine - just milled 2mm from 62t cylinders - i will use LA freestyle sleeves(that will go directly in the 62t cylinder casting without other mods) with 85.5 wiseco pistons.I know how to do crankcase porting and exhaust porting - i have a copy of racelogic templates.
What else should i do from your experience???
