Yea, I was sitting in the driveway, I let it idle for about 5 minutes to get it warmed up. Then tried bliping it, and it would stall out. I could open it slowley and it would be ok. Before I cleaned the carb and took it apart completely, it would stall or bog on the trail when I wacked it full open. The bike would pop start itself while rooling stall and just stop. But hey I have electric start!! The other thing I want to do is trim the throttle stop from 20mm to 18.3. I dont think I can get the .3 but say in the general area. When I was reading the Dynojet web site on the stage 2 kit thats what they were doing. I read some other posts over at thumpertalk about doing it also.
