What is the proper jetting for a White Brothers e series slip on. I have a UNI and the air box lid is on. Right now I have a 38 pilot jet and a 145 main jet. It seems to be running hot? Any help would be greatly appreciated.

 

Years back when I was messing around with sport machines I used the UNI company for their rebuild kits. I would contact them and tell them what machine, engine and what mods were done and they would send me a complete kit for a rebuild including jets along with setup instructions. I never had a problem with them and the kits worked real well.

 

Jetrus has a kit for these that have aftermaket parts.https://www.jetsrus.com/a_jet_kit_at..._1999-2008.htm
