Red Hot Rephased XS650 Engine Hugh's HandBuilt 277

This engine came to us as a bit of a problem engine really. Customer brought it to us, as another shop had tried to build it, and looks like they were simply in over their head. Things were shimmed wrong all over, the clutch was assembled incorrectly, the valves were hitting each other, the cam was too aggressive, shift shaft was binding in the cases, etc... We tamed it down a bit and brought it to life. Hugh's HandBuilt 277 Crank and Camshaft, oversize valves, 5th gear OD, all of our clutch tricks including a "7 into 6" HHB Clutch swap, 750cc Heiden Tuning Big Bore, Pamcopete 277 Ignition, HHB Permanent Magnet Alternator swap, and of course all of our standard rebuild tricks - enjoy and thanks for watching.

PS - don't mind the oil leak from the oil filter cover, the owner has a custom oil cooler that will be installed there - so I just used a junk cover here for initial fire.
