after removing the rust best i can from flywheel, i paint the flywheel,. nice coat of Rustoleum, whatever color u like. then with some of the OOOPS paint from HD i paint the fin that is TDC. actually,i paint the fins YELLOW since i run them for a bit w/o blower housing on test stand... to make sure they run... and then paint the TDC fin with another color so i can tell at a glance which way is up. isnt the groove for timing and drive key, on both the flywheel side and work side... TDC?
try not to be like the HD rider who at a party, HD running, NO BELT GUARD tween engine and trans... "what this?" reaching down to touch...
