HOWDY from Texas ! I Just picked up my 1st Harley. One of the only ones I'd ever realistically want. A very clean 99' X1 EFI for a song. Blown out rear head gasket. already got back piston head off. Had thoughts of only rebuilding the back piston. Was told not to by a Harley tech buddy in another state. Bike has 20k. Very clean motor. Next steps, pull the front head & jug if I am going to rebuild the front one as well as the back. Check jugs, heads, valves, hone, New rings, insulate exhaust, perhaps put a better EFI controller on it. Performance Muffler, I need a Front Rotor, valve cover breather bolts, a gasket set, a ring set, a new clutch cover, ( an eagle one? ) spring compressor......... ??
