KN Filter Jetting

Recommended Posts

03 KLX 400/DRZ

Installed KN filter and now I have hesitation off idle(0-1/4 turn)

Dealer said "that's a four stroke for you"

Bike didn't hesistate with stock air filter.

I like the added power of the KN past 1/4 throttle

Jetting suggestions?

Lean Pilot?

Everything is stock with the exception of the new air cleaner

Any help would be appreciated

Thank You
