Tusk Fuel Mixture Screw

Recommended Posts

Hi guys,

Just installed one in my 2007 CRF 450R last night,haven't tried to start it yet but have it turned two full turns out so should be somewhere in the ballpark(stock motor[38 hours]with a Leo Vince X3 exhaust)?Found a couple of videos on tuning with it so should be ok there,any tips on getting it dialed in?I'm at 1,400' elevation and plan on hitting Gorman this fall(3,800'+ elevation)with a mandatory spark arrestor and imagine I'll have to lean it out a bit?

Since Bill B is a relatively close neighbor and has the same bike I'll be picking his brain if(when)I run into issues,in exchange he can run the snot out of my Busa.:rolleyes:
