[eddie1]

motor just won't idle.....i play with the air/fuel mixture screw no help im thinking it needs the jet needle clip moved eather up(lean) or down(rich).

Everything stock onthe big motor wise, and stock settings, its average about 70-80 degrees were i live, 94 octane gas mixed with castrol 936(rough guess of what number it is)

just looking for some oppinions on this

The genuine 2-stroke wont idle mine doesn't, unless it suddenly dies as soon as you let off the gas then i wouldn't worry about it.

It wont idle even if you set the idle real high?

What happened to the pilot circuit. You have idle issues, its not the needle!

my cr125 wont idle either its just about impossible to get them to idle it takes a lot of time and and practice to get it to idle its not realy worth it to me im not realy in many situations were i am idling

Its impossible to adjust because the pilot is horribly WRONG! Most bikes adjust to around 2 turns. If you have to turn it in under 1, you need a bigger pilot. http://www.dirtrider.net/forums3/showthread.php?t=159938&page=1&pp=20

My bike won't idle whatsoever, I leaned that thing out until it started surging when you were riding and let off the gas and pulled the clutch in. Bumped it back up a couple sizes, real crisp throttle respons off idle, but it won't sit there and keep running after a few seconds.

For the record, I have never set the idle on a 2 stroke, NEVER! A 4 stroke needs the idle set super high, to negotiate a track, or it will die. I am damn near as old school as it gets, you turn the throttle. You guys thread jumping, check your specific carb, it may not even have an idle circuit, it could have a slide stop adjustment. If you want it to idle while you are running into a store for a pack of smokes, quit smoking! Eddie1's issues were different, in than it would not idle because of the needle, was way off!
