low end bogg

[goldbergrx1]

i just had the k&n air filter kit installed and the sled has a low end bog...almost like its starving for fuel....sometimes it feels like it wants to clear up but then it doesnt...if im going slow, say 10-15 mph, the sled has little power...it takes a second for powerto spool up then it kicks in like a bat out of hell...this off the line bogg is bothering me though...can any of you tell me whats causing this?

Did the filter kit come with jets and carb. springs. Sounds like its lean.

You may want to double check your coils to make sure they are completely seated and have not come loose. Yamaha finally wised up about this problem and decided to bolt the coils in on the new models.

Probably need richer pilot jets.
