i have an '03 raptor...i recently put a pro circuit t-4 pipe on it, rejetted the carb to 150 and 155, and put a K&N powerlid on it. it runs awesome. however when i completly let off the gas, it pops a little. im pretty sure that my air/fuel mixture needs to be adjusted. i am not sure which way to turn the screws...any help would be appreciated

 

Unscrew them out about 1/4 a turn on each one and try again. You need more gas flow.

 

is that correct? i thoguht the more you screwed them out the more air it let in?? can anyone else answer this?

 

On the Raptor, you turn them out for more fuel.
