Bike only has 42k,ran good,but for only about 20min at a time or until the battery was drained,Replaced the stator,engine almost started kicked oved about 4 times ,now won´t turn over even with the plugs out,I´d hate to have to take the engine out of the frame again,but I might have to,timming belts weren´t moved,something seems jammed,any ideas anyone?
