ok guys need some help here im stumped!!

[Beamesy7]

Quad was running lean at an idle and makin header glow and breakin up a little bit under throttle, so i upped my pilot to a 45 and my main from a 147.5 to a 150. I have a full dg exhuadt front to back and air box lid mod with a med flow filter. Now it wont idle!!! Ive had the carb off three times today and everything is working properly and is clean!!!! Intake boot is new, im so ******* confused here what could have change so much? Ive tried adjusting idle screw and air screw with no changes, even replaced choke assembly because ive had the same problem in the past with my last warrior, and it was the choke lever and orings!!! Any ideas, im in the shop now so fast response will be much appreciated! Was supposed to go ride with the friends to day and ended up having to take the old ladys dvx 300 YAY!..... NOT!!!! Thanks, beamesy7

check to make sure your accelerator pump rod isn't stuck

Got the o ring in the new boot?

 

[Beamesy7]

Yep new orings with the boot and wouldnt the accelerator pump make it run rich and bog out not race?? Just a question. Any help i will check.

 

[lbjamm]

Is the idle high or won't stay running?

 

[lbjamm]

Maybe throttle cable hanging up

 

[Beamesy7]

High as hell, and it tries to rise if i let it run too long

 

[lbjamm]

Did you turn idle mixture screw in to lean it out?

 

[Beamesy7]

Yes tried turning it in and out and everywhere inbetween doesnt change a thing.

 

[lbjamm]

I'd try going back to other pilot and see what happens.

 

[lbjamm]

Did you change the needle setting.

 

[Beamesy7]

Needle is at 3rd setting like most of us run em at, i have the carb apart now and dont see a damn problem. The 45 i put in is brand new mikuni equiptment. It was running wayyy too lean with the stock pilot

 

[Beamesy7]

Ok is the needle supposed to come dowb in full contact with the main jet or should it have a gap?

 

[YAMAHAULER]

it should go down inside the main jet

 

[Beamesy7]

Ok mine isnt doing that, BUT it didnt in the 147.5 and idles and ran fine

 

[Beamesy7]

Ok, accelerator pump is working fine also. Should i drop the needle a notch? Doesnt make sense, running lean would cause a high idle, not rich, and i upped everything.

 

[Beamesy7]

???????

go back to your org pilot add idle fuel with mix screw 1st . It ran there check your plug at id and 1/3 throttle hold at cruse speed rpm and kill mtr to get good reading cardboard brown is good white is lean . the needle has to be in the jet it is 1/2 of it at closed it will be most of the way in at WOT just the tip should be in ,if not check the install .

 

[Beamesy7]

I tried switching back to pilot jet and adjusting everything all over agin made no difference still idles very high. Runs great other that has power all the way up through just doesnt go down to a typical idle like it should.

Your sucking air from some where then. From either your boot or the o ring on your boot.
