im ordering a K&N airfilter for my raptor 350 and im wondering if there are certain size jets for it and if so what size? and also this is the first time im ever doing something like this so can u give me anyhelp on how it do it ? is it easy? is it easy to mess up? were do i start

i have nooooooooooooo clue so any comments or help will be greatly appreciated

 

well if your adding a k&n i recommend modding the airbox for better airflow, and with that type of mod you will need to rejet, i believe a dynojet stage 1 is what you need, or you could hit the local dealer and buy several jets close to the main jet you have now. that is the best i can do because i dont know much about jetting but you could take you bike down to the dealer and have them rejet it and save you some time.

good luck.

also does the rappy 350 still have that horrid airbox design like the warrior and wolverine, where the lid holds the airfilter in?
