ok well i have this z400 i have been having problems with
at first thought it was stock carb so i got an eddie for it that didnt work come to find out it was a bad pro-com box. Now it runs good untill warmed up for 10-15 minutes carb set 12 click and 2 1/2 out screw.
what it does is just stay reving real high un till you let it cool down for awhile
checked the throttle shaft works fine.
does any one think it could be stator?
any ides or pointers would be helpful.

The edelbrock is notorious for having a "Hanging high idle" do a search on here and you will find several different fixes for it. The carb is a good carb! Just need to tinker with it to get right.

Sounds like the accelerator pump shaft may be sticking. Take your seat off and try to return it to idle by hand.

Still check the accelerator pump linkage. I had the umbrella seal go bad and it made it stick, and have a very high hanging idle unless I manually returned the wheel. If you ever need parts for it, ATV Galaxy is the only place you can get them now.
