Here's the quick and dirty: Crash caused coolant leak while riding, didn't notice, bike overheated, had oil in air box. Replaced radiator, started bike and it started blowing white smoke. replaced head gasket, piston, piston rings, and rebuilt water pump, checked all valves and got them in spec. bike was running great but after 10-15 mins of riding bike would stall at idle. Figured it just needed a carb clean and a new pilot jet. Took bike to work, cruising at 50 bike started sputtering, thought i hit reserve and switched petcock over, bike still died and wont start up again. Also noticed now while in gear with the clutch lever pulled in, bike is hard to push. i installed a trail tech stator and reg/rec about a month ago, and a new tusk lithium ion battery about two weeks ago. i have a new JD jet kit on the way and will replace the vacuum lines when i pull the carb. I have also pulled the fuel line off the carb to test fuel flow from the tank, which was good. Please help, i never get to ride this bike because im always fixing it.
