I work for a custom atv shop and i am in the process of building a street legal quad with an r1 motor in it. i have a couple of newbie questions since we have never dealt with the motor. first off can the air box assembly be deleted? i was told it could by a motorcycle shop but now that i have the motor here there is a lot going on in there and i would imagine it would cause an issue. secondly will the motor run properly without the factory guage cluster being plugged in? lastly i was also told by this shop to just delete the exhaust gas sensor. is this recommended?
