I just got a ENM tach and it is reading 1500 rpm at idle. to me this seems a bit high. What is the right idle for these things? Is there anybody who knows the specks for a 66cc?
There you go. There's no better answer to your question. Forget what the tach says. Rely on your ears and how the bike performs. If it stalls, increase the idle speed. If it doesn't, decrese the idle until it does then increase it until it doesn't...then go ride and forget about the instruments. (sort of like flying VFR)I don't at all mean to sound like a smart as* but if it is idling to high it will annoy you and if it is idling to slow it will annoy you . If it idles perfect it won't annoy you .

i almost agree with Nougat. my idle is set at "just a little bit higher than enough to keep it running."
sometimes if i come to a quick stop my idle will drop, probably from fuel sloshing around in the float bowl, and other times, if you misjudge your start, you'll kill the motor from dropping the clutch too fast. if the idle's a little higher, you can save it without stalling.
with a well tuned bike i can get the idle down so low you can barely tell it's running, but the rideability will suffer.
as long as it's not revving way up, or bogging too low, you're good.
as far as specs, i doubt there are any.
