bansheenoob Posted May 17, 2012 Report Share Posted May 17, 2012 (edited) I'm asking myself if turning air screw clockwise on my carbs are supposed to make the engine idle lower or higher??! It seems for now that clockwise is making the idle higher??? Its like the engine is at 1/4 full throttle without touching the thumb!! Thing is I'm living in city and the noise its making is crazy!! So I cant test things for a long time and I dont want to damage beeing lean. I'm looking for any tips guys!!Theres not too much on idle problems on google.. Could it be that the throttle cable is totally unadjusted? Air leaks even if everything is tight with the Boss intake? Jets really off? setup: stroker 385cc cool heads Vforce 3 starts very easy carbs are cleaned jets are pilot 50 and main 110 +4 timing T5 exhaust Boss intake 2 in 1 filter brand new plugs living in Quebec canada, not sure of elevation. Now hot/humid/warm out here but it can go cold anytime.. Edited May 17, 2012 by bansheenoob Quote Link to comment Share on other sites More sharing options...
andrew3160 Posted May 17, 2012 Report Share Posted May 17, 2012 Clockwise = higher idle Quote Link to comment Share on other sites More sharing options...
shakar Posted May 17, 2012 Report Share Posted May 17, 2012 (edited) yup i agree take the filters off and take a peek to make sure the slides are all the way down. then sinc/ajust as needed.theres also the option of a snail lookin carb sinc tool. if thats not it .pos air leak so look into makin a leaky down test..or youll blower up. gooodluck Edited May 17, 2012 by shakar Quote Link to comment Share on other sites More sharing options...
bansheenoob Posted May 17, 2012 Author Report Share Posted May 17, 2012 Clockwise = higher idle LOL thats why the idle was stupid high!! do the slides go completely down when you are not giving it gas? another thought is air leak I'll have a look if the slides go completly down, but what is the normal air gap when throttle is at idle? is it completly shut? yup i agree take the filters off and take a peek to make sure the slides are all the way down. then sinc/ajust as needed.theres also the option of a snail lookin carb sinc tool. if thats not it .pos air leak so look into makin a leaky down test..or youll blower up. gooodluck How much it taes to damage an engine running a bit lean? I never went on a ride, just idled 2 mins max...I'll try to sync the carbs to.. thanks for all the good advice Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted May 17, 2012 Report Share Posted May 17, 2012 Whenever you make an adjustment give the bike a few seconds to catch up. If you turn the idle down don't expect instant results. Gas it, let it come down. See where your at. Quote Link to comment Share on other sites More sharing options...
bansheenoob Posted May 17, 2012 Author Report Share Posted May 17, 2012 (edited) Ok! Now the idle is fine, a bit low, but 10000x better!! The idle screw and the air/fuel are 3 turns out and the custom adjustable vent carb valve too. BUT, I drove it around my house and let it idle for 10mins and stopped it. After, I started it again with 1 easy kick and let it idle for 1min, then 1/4 throttle and the Banshee made a deep tone, like it was too rich and just drown in fuel. Now it just wont start LOL!! I guess its tune time.... Edited May 17, 2012 by bansheenoob Quote Link to comment Share on other sites More sharing options...

vulvafan537240 Posted May 18, 2012 Report Share Posted May 18, 2012 clockwise on the air screw makes it richer. if youre at 3 turns out, you need a bigger pilot jet. where was the air screw before? i think you should go back to where it was on the air screw and adjust the idle screw and possibly the throttle cable at the throttle housing.

bansheenoob Posted May 19, 2012 Author Report Share Posted May 19, 2012 Ok bad news are in; there is no more spark what so ever so its not a carb issue. I tried switching spark plugs and by passing my kill switch(old piece of...) but nothing.. I'll make another post in the repair section..
