alright, I am looking at removing the air box and putting in a K&N style air filter to replace my current one... since this will be a change to the air intake (more air)... will i be running too lean or rich, and i bought the quad from a guy who previously rejetted the carb.. it was tuned to an FMF Slip on...


so should i rejet or not?

yes, you will want to rejet..you will be lean. does it still have the slip on? I would pull the bowl off the carb and see what the jetting is now. There is a chance you don't have to depending on what its at now.

you want to remove th whole airbox? or just the lid

look in the jetting database tons of info and different setups

on my gf's quad, I had to put a 22 pilot jet in there with the airbox lid off. the needle and main were from the dynojet kit.

idk what is best lol

yeah the FMF 4.1 SL Slip on is still on,

i could check...


I also do alot of mudding and sand/gravel riding, so would it be bad to take the air box off? because i would be royally screwed if anything got in the carb...
