sl0wp0ke Posted June 16, 2013 Report Share Posted June 16, 2013 I have a 99 banshee. Stock carbs, vforce 3 reeds, fmf pipes, k&n filter and powerlid. Ride at sea level. I just got theese carbs and trying to get them tuned in. I have cleaned carbs, air screws are 1.5 turns, 3rd clip on needle. Slides are incorrectly carbs are synched with tool at idle and rougly 1/4 throttle. Compression cold is110 on both. Both pipes apear to smoke evenly. I mix ams oil 32-1 with 91 octane. 1st try.. 300mains 27.5pilot. Bike started great. First part of throttle ok but boggs and could not hit powerband. Ran about 180-204f. 2nd try..280mains 27.5 pilots. Same started and begginging of throttle. A min powerband on flat, bogged bad on hills and worked alright downhill. A big improvment over first try. Ran about 140-160f Sence the bikeworks so shitty I only drove for a few minutes. Both plugs didnt seem to be chaging colors at same rate. 1st one the brakeside was leaner and second run clutch lever side was leaner. How long do you need to ride the plugs to get a good reading? Am I on the right track? I want to try 270 next? How close on main will I need to be to get a powerband? Any help would be great. Quote Link to comment Share on other sites More sharing options...
kedge82 Posted June 28, 2013 Report Share Posted June 28, 2013 to gget good readings on plugs you need to ride wide open through wahtever gear u can make it through while at at high rpms kill it and coast to stop and then check. mine is bored 60+ with fmf sst carbon fiber reeds stock carbs at about 800 ft and run 290m 30p needle on 2nd up. try a larger drop in your main Quote Link to comment Share on other sites More sharing options...
