With the stock exhaust mine ran fine after upping the pilot jet to a 42 and everything else stock. With an MX pipe, run a 45 pilot, needle raised 2 grooves, and 195 main. I'm at 300 feet.

Std jetting for any model can be found by downloading the owners manual or the service manual for your bike at the factory Husaberg web site. You will need to read them both to keep things in top shape throughout the years.
