Hi group . well had scooter out this past week and this week got a small issue the idle will not idle completely down at random times. I can stop at a light and it may take 10 or more seconds to idle down.its not a screaming high idle but maybe 100 or so rpm. Higher thats a guess Or it may not idle down or it may idle down normaly.now since this has started I also noticed if I rev it up at random times again. I will get a pop in the engine like if you tried to rev it before its warmed up.hope this isn't something critical. Only 1000 miles on plugs.bike miles 19600.
