CRF's Only Forums

Hello to all you experts.
I have an 06 CRF450X. I have the stock pipe with the baffle out. Took off the smog pump. I am adding the boyesne accelerator pump, I figure I should open up the air box and jet the carb. My question is. "What Jets?"
thanks so much.

Welcome to the site. Please take a look at the HOW TO: CARB JETTING DATABASE sticky in the 450X forum and you will see a lot of info. Check that out then ask questions.
