I have an 02 xp that was bogging down last summer getting to 55 then up to 64 then back down.. When i first purchased it it was 68-70 mph all day long.. Im taking the carbs out and cleaning them, i just bought carbon tech reeds im replacing them so i just bought the carbon tech sense they are about the same price as oem. Anyways what im getting at while i have the carbs off what other upgrades can i do? Ive heard jets but dont know what to look at.. I already have the R&D filter too..
