Ok, so I replaced the fuel screw assem. tonight (spring, washer and "o" ring) with an adjustable unit. Fuel screw was set at 1 turn out from closed. Manual recomends 1 1/2-1 3/4 from closed. Tried setting it where it was. Then the factory settings and bike still hard to start, Wont even try with choke on?????I'm Running out of ideas now. Get the bike started after what feels like 50-60 kicks. shut it off and immediately kick it again and it fires right up. let it sit for 10-20 minutes fires first kick with no choke or hot start?? Could it be low compresion, carb issue, ignition???
