I have a new problem: occasional poor idle. Most of the time this scoot idles very smoothly with no issues. But occasionally, it gets very rough at idle and dies unless I keep some throttle on. It seems go like this for a few hours or maybe a day and then get better again. It seems as though the engine is not getting good spark. I've checked all the connections and they seem to be OK. I plan to change to an Iridium spark plug to see if that is of any benefit. The scoot has 4,000 km on it with the original plug.
Any other thoughts? Thanks! Gary

Increase your idle rpms, they tend to drop over time. Should be 1500.

Jacine, The strange thing is that the idle is fine most of the time, then occasionally the engine runs very rough. I've noticed a drop in gas milage too. So that makes me suspect something electrical, like a spark plug or coil going bad.

The iridium does smooth out the idle, but doesn't do anything for power.

I installed an iridium spark plug Friday and the scoot seems to be idling great. It also seems to be a bit livelier (more power) though that may be in my imagination. Of course the bad idle came and went sporadically, so it will be a few days before I know for certain that the new plug solved the problem. But for right now, scooter life is good: - The charging system works (new diode and battery)
- The tires hold air (new valve stems)
- The coolant system doesn't leak (bypassed the carb heater)
- The scoot idles great (new iridium plug)
Cheers, Gary

Check your vaccume lines & make sure the bands around the carb and intake manufold are tight & air filter..
