You probably need to richen the fuel mixture a bit. You might want to check out XIED'S at nightrider customs. Do a search and you will find more info. The XIED'S worked for me.

 

it ran fine for 12000 miles then all of a sudden started could it still be a lean condition thanx for everyones help ride safe.

 

What does your dealer have to say about that? How can it be normal if it just started? I can tell you, that if it is stock, it is most likely running lean. I don't know why you wouldn't have noticed the surge in the first 12000 miles. Check your plugs, probably snow white or burned up from excessive heat.

 

Ditto what others have said. Richen up that AFR and I'll bet she stops surging.
