When I get on my bike and try to ride it feels like it is running on 1 cylinder. You can smell it's rich and see the black puffs of smoke when I shift. It runs so poor I can barely pull out without stalling. I have to ride the clutch bad. Any ideas of where to start looking? Around 140 degrees it backfires a bit not hard but a bit and then it runs fine again.

sounds like fowled plug

that was gonna be my first step. pull plugs, replace and see what happens. if that isn't it. i'm not sure where to start, maybe the dealer this time huh??

is there a chance an old battery could cause this issue

Hmm, I doubt it. If it has enough power to start the motor, I'd think it has enough to run the electronics properly.

thanks

I put in the new plugs yesterday and it runs great. Thanks for the input. Now lets see how long they stay clean...?? The plugs look like it has a running rich issue. But I'm not the first owner so I'll see what they look like in a couple thousand miles and go from there.
