Hey I have an 07 predator 500 with stock air box but k&n filter in it and complete DG exhaust. I think the quad runs great but am worried about it being too lean I have stock jets in it and am wondering if I should change the jets to be a little more safe? If so what type of jets would I need

 

do a wide open throttle run asnd shut it off and see what color the plug is, should be a lite brown.

 

ok thank you i will try that out
