pr0blumz Posted May 2, 2008 Report Share Posted May 2, 2008 Hey guys. I recently bought a '02 and found that the mixture screw on the carbs are turned all the way in. Are they suppose the be like that? If not, what should I do to correct the problem? I'm not mechanically inclined at all and any help would be greatly appreciated.

98_shee Posted May 2, 2008 Report Share Posted May 2, 2008 They should be around a 1 1/2 out, you may need a bigger pilot, what is your current jetting, and mods, does the bike idle now? Quote Link to comment Share on other sites More sharing options...
pr0blumz Posted May 2, 2008 Author Report Share Posted May 2, 2008 They should be around a 1 1/2 out, you may need a bigger pilot, what is your current jetting, and mods, does the bike idle now? I don't know the current jetting. The mods as far as i can see: air box & tors removed, t5 pipes and boost bottle. The idle is fine but when I give it a little throttle, It bogs but still run through all gears. When idling i cant hear the "pinging" in the exhaust like my cousin's. He only has pro circuit pipes and jus blows by me! Quote Link to comment Share on other sites More sharing options...
pr0blumz Posted May 7, 2008 Author Report Share Posted May 7, 2008 (edited) I forgrot to mention I have vforce3's too. I pulled the carbs and the mains are 280 & the pilot are 25. What are your suggestions now? Thanks Edited May 7, 2008 by pr0blumz Quote Link to comment Share on other sites More sharing options...
rubberneck Posted May 8, 2008 Report Share Posted May 8, 2008 T5's with air box removed (i assume that means it has k&N pod filters right?) If thats the case and you are at or near sea level, you are lean. I would go up to about a 320 on the main and see how it runs. you may need to raise the clip on the needle a notch or 2 after you go up on the mains.

pr0blumz Posted May 8, 2008 Author Report Share Posted May 8, 2008 Yes, the carb has uni-pod filters and I'm @ sea level. I was thinking a 27.5 pilot also because if I had the air screws turned 1.5 turns out, I couldn't start it after let it sit 10 mins. after doing 20 of riding w/o choking it to crank it. Like I said before, the air screws are turned all the way in now on both carbs and that's the only way it will crank without having to use starter fliud and restart on first kick after getting warm.

BellicoseBanshee Posted May 8, 2008 Report Share Posted May 8, 2008 Yes, the carb has uni-pod filters and I'm @ sea level.

Like I said before, the air screws are turned all the way in now on both carbs and that's the only way it will crank without having to use starter fliud and restart on first kick after getting warm. Turning the air screw clockwise reduces the amount of air and turning the air screw counter-clockwise increases the amount of air in the pilot system. Warm up your engine, then adjust the idle slightly higher than normal. Turn the airscrews in until they seat and then back them 1/4 turn and let the engine stabilize. Keep turning the airscrews out a 1/4 turn at a time, allowing the engine time to stabilize between changes, until the engine reaches its highest RPM. The air screws should be between 1 and 2-2.5 turns out. If the highest RPM is less than 1 turn (lean), install a larger pilot jet. If the highest RPM is more than 2-2.5 turns out (rich), install a smaller pilot. No need to guess... :thumbsup: Quote Link to comment Share on other sites More sharing options...
pr0blumz Posted May 8, 2008 Author Report Share Posted May 8, 2008 Well, I know I need a bigger pilot becuz I've done that already and the idle gets worse when I start turning the air screws out. Quote Link to comment Share on other sites More sharing options...
pr0blumz Posted May 13, 2008 Author Report Share Posted May 13, 2008 Well, I bought a jet kit and changed the pilot to 30 and the main to 300. The carbs idle pretty good with the air screws 2 turns out. For the best idle though, the air screw on the left carb needs to be turned all the way in and the right side needs to be turned atleast 3 out? Any suggestions?
