I am thinking of switching to a dual stage UNI air filter. My question is do I need to rejet or am I ok? This is a bone stock machine. Thanks.

 

I installed one on my Kodiak. I was rich before with stock filter (sparkplug real black). After installing the UNI it is now grey/white. Its on the verge of being too lean..Once in a blue moon I now get a backfire. I think I'm ok and not to lean but not 100% sure. It rides great and has lots of power now.

 

Thanks.
