I'm having the worst kind of problem, an intermittent one. It's been going on for half a year but I can go for weeks without a problem, and then all of sudden, the throttle fails to produce an response. Sometimes, I feel the motor start to engage and stop and start and stop. Then if I hold the throttle open for a while, sometimes as long as a minute or so, the scooter will slowly start to respond. Then, more often then not, it will work just fine for the next few days or weeks. I have power to headlights, battery meter, etc, all of the time, it's just power to the motor that is seeming to fail.
I've had Electric Motorsport look into this but they didn't have the problem during testing and they didn't find anything wrong.
It seems to happen more frequently when it's raining or has recently rained but then on a day like today, it works fine in the rain without any problems.
I'd be grateful for any ideas on what might be wrong and/or what I should do to try to figure it out. It's pretty scary when I'm riding along at speed and it suddenly fails! So far I've been able to get out of the way of traffic without incident but don't want to wait till my luck runs out!
