Does the bike still have the choke lever (idle advance) on the handle bars?

its the plunger at the end of the cable from the high idle lever (idle advance) on your handlebars. It goes into the throttle body. Follow the cable from the handlebars to the throttle body (fuel pump side) and you will see it. Do a search here to find many different ways to BLOCK it off. Or, get the Yoshi one.

just unscrew the cable and take the plunger out...if problem still exists....continue your search for an air/vacume leak/pinch

The plunger may be stuck in the open position., Or you may have an air leak.
Does anyone know where I can get the plunger and spring to put back in with a screw cap? I recently got my quad back from being stolen in 2008 I finally got to the point of starting it and it starts but the idle is high, there is nothing in that hole, any help would be appreciated
