New pipe, what to do to jetting?

Recommended Posts

I have an 05 crf 250 R and got a big gun evo X (just the slip on), right now i have stock jetting and ride in the high desert (3000 or so elevation). The jetting suggestions is not on the big gun site yet so i was just wondering what I should do to my jetting?

I checked their website but all they really mentioned was info on the - '04 CRF450's :naughty:

It's looking like a 170-175 main jet though, but I think that close to stock on your model.

At the top of this page is a topic ' Jetting Settings '. There's some really good info in there that I'm sure you can team up with. Jetting Settings
