Hey folks,
I've seen a couple posts about this problem but no resolution. I just bought a used People 150 with about 3k miles, and the previous owner claims to have taken great care of it. It runs like a dream if I keep it below 45. However, after about 4-5 minutes of going 55+ mph, it starts behaving funny. The engine seems to lose power intermittently, like a bad shift would feel. It kind of jerks slower, then keeps going. The first time I had no idea what was going on, so I kept the throttle engaged, and it kept happening until it stalled. Since then, I've just eased off the throttle to 45-50 mph, and it seems to do better.
I've tested it without the gas cap on, but it still happens, so that eliminates some potential causes. I'm also relatively light (145 lbs), so I don't think the scooter should have a problem doing 60 mph with me on it.
Any ideas what could be going on? Dirty carb? Could this be a sparkplug issue?
Thanks!
Sean
