i re-jetted my 05 xr650l with a dynojet, and yanked the smog pump. it seams to have a little hesitation at low rpm, will the mixture screw smooth it out? it still has the tab and the screw is out 2 1/2 to 2 3/4 turns. i dont really want to pull the carb, and then the bowl to turn it past the freggin stopper. if it will fix it then ill just grind off the tab.
