Just picked up another Sp1. Has 15k miles on the clock. Jardine 2 into 1 and a power commander 3r, flapper mod, soft rev, all that stuff for motor mods.. Bike sat for over a year when i got it. It started perfect at the guys house and ran great on the ride home. I put fresh gas in it that night, and The next day i threw on the leathers went for a little more "spirited" riding. Thats when the bike started cutting out/ sputtering a little around 6k rpm. And if i pulled the clutch in to coast on a straight the motor dies. Same thing when i stop and idle. And when i try to start it back i have to give it some throttle to get it to fire. Could this be a prob with the Power commander? or smething else? I changed the plugs and cleaned the filters and adjusted the idle up yesterday. It idles now, A bit high, but still wont start up without twisting on the throttle. Just lookin for ideas. Thanks in advance fellas.
