1991 Kawasaki AR125 (two stroke engine problem)

[richardosborn...]

Hi guys.

Am new to this forum, and in need of some guidance. I recently bought a 1991 Kawasaki AR125 and have had a few problems with it in terms of restoring it, but this one is quite weird.

When the engine is started, it sits idle at around 1000rpm. When I open the throttle, it revs up and very slowly moves back down eventually settling at 3000rpm instead of 1000rpm. It sometimes will go back down to 1000, but usually stays at 3000 until you let the clutch out in gear.

Any ideas about the slow rpm come-down or 3000rpm idle?

hi, to me that sounds like an air leak-but also on my vfr if i whack the choke on fully, and i let the revs go up, my idle because of the rich running is higher.

thanks
