I recently purchased a 1985 Suzuki DT85 for a very low price. When I first ran it, it would only run on 1 or 2 cylinders. When I tried running it with wide open throttle, it would of course run lousy, but it would have difficulty returning to an idle speed. Even after returning the throttle to idle position, the motor would continue to run at high RPM's for a long time if I let it (I've let it go about 30 seconds before shutting it off). <br /><br />Since then, I have rebuilt all 3 carburetors (which were filthy by the way). It now runs quite well on all 3 cylinders, but the throttle problem remains...its even a bit worse. After I return the throttle to idle position and the carb flaps close, the engine continues to run at high RPM's for a long time. <br /><br />Any hints? Could this simply be a carb ajustment problem? Do I need to buy a timing gun and mess with that (I borrowed someone's gun, and the timing appeared to be only slightly off from the factory norm)? Could it be anything else?<br /><br />Thanks for your help!
