what up guys/girls i have an 05 f4i and just got a new slip on from a friend of mine but on f4is the o2 sensor is on the mid-pipe. the slip on has no place for the o2 sensor.I guess my question is do i need the o2 hooked up? cause it seems to run fine w/o. And am i hurting my bike by not having the o2 sensor hooked up?

 

hey man whats up? only the f4i's from CA have an oxygen sensor. the slipon doesn't have a bung hole cuz its for offroad use.

 

hey hey whats up! but it wont **** anything up right?
stupid california smog crap
