Do you have to rejet with a K&N kit?

if your asking if have to reget with the kit you get from k&n, no, you can go to your dealer and get a couple jets, its alot cheaper

but if your asking if you need to re-jet with a K&N air filter, yea, it would be wise to its not neccessary

did you get the jet kit with the filter? if not, then i would just put in a 150 keihin mainjet. you could also put a 40 or 42 pilot in if you wanted.
