ARRRRGHH, finally back on the bike after a broken foot & the 06 TE450 starts knocking on the right side, limp home to find a very hot, very unhappy engine. Seems in conversation with Uptite's George that my main bearing has decided an early retirment option was a good choice. I'll ship it to Fla if I extract it,,, Anyway, anyone got a source for a 06-07 (preferred) TC 450-510 engine. By the looks of the $$$ for a rebuild I'll be buying another bike, new leftover or a garage queen,,, knockin around the idea of a simple motor swap sounds good though. Thanks.
