Rode last wed with no issues other than I was low on gas and too lazy to get some. Didn't ride until last night to get gas so I could ride to work today. There was a little sputter and hesitation on my way but seemed ok on the way back, a 4 mile round trip. This morning it did a little jerking and popping under acceleration but seemed to settle down at speed, after work shot went crazy. Sputtering, popping, hesitation, jerking, backfiring, stalling, over revving to hit the rev limiter, you name it. Don't know what the hell is going on so left it at a shop. SUCKS! I know if I started to "fix" I would just get frustrated and make it worse because that's what I do, so I'm going to pay out the ass, but at least someone who knows what they are doing will look at it.
