I have recently changed my spark plugs for the first time and noticed that they were black, there was no damage or build up, just the black color. There is only about 30 hours on the bike so far. I have since removed the air box lid and snorkles but the performance seems to be about the same. I checked prevoious posts regarding re-jetting and was wondering if there would be any benefit to adjusting the carb the with the stock jet/clip or should I insatall a new jet? Does anyone know what elevation the carb is set to operate in from the factory or what the stock jet size is? I live about an hour north of Tampa FL and the elevation here is 200ft above sea level. Also I checked RM for the K&N filter/jet kit and it looks like they only sell the filter with no jet kit. Is there somewhere else to purchase the dynojet kit? Thanks for any help.

 

When you opend the airbox you rais'd the air flow, so now you need more fuel, go up a jet size or two, you can get a jet kit from rocky mountin atv, here.

Were you refering to the FMF kit? That seems to be the only one I can find besides the dial a jet.

 

No, the k&n jet kit, go to catalog then in there go to intake, there you find the k&n atv jet kit, i guess the fmf jet kit will also be fine, but for some reason it costs more....
