Jetting on a KLX450R

CRUNCH · 12-30-2008, 04:36 PM

Put a Pro Circuit pipe on the KLX with a Dynojet jet kit. I tried the airbox mod, but it is waaayy too lean. Even with the largest main jet (160). Just wondering if anyone else has done this, and what the outcome was? I've got a glowing head pipe! Thanks.

I bored the main jet out with a 5/32 drill bit. Problem solved!
