XR650 - Jetting with Big Gun exhaust system?

[twinpoint]

Hi,

Can anyone tell me the jetting set-up for a 2001 XR650R that has been uncorked and has a Big Gun pipe and silencer?

I have a 175 Main and 65s pilot now and the bike runs way too lean throughout.

Thanks,

Rich

Looks like you're running what Baja Designs recommends to get you in the ballpark. Sounds like you just need to get a few different bigger jets and move up until you get it right. :cool:

Have you drilled out the side cover?
If so, yea it'll be a little lean.
Try a 185.

Airbox panel has been drilled out - I will try a 185 main
