Alright, I have a brand new problem. Fancy that. I was riding across town when I started hearing a sound under my side cover--it sounded like the belt was dragging on the side. Then it started bogging down until it finally stopped. I took off the side cover and found that the belt really wasn't turning all that well. Then I realized that the rear pulley looked like it was rubbing against the frame of the bike, but it was rather hard to tell. I also realized that there was gear oil dripping out the plug hole.
I was a little concerned yesterday when I pulled out the gear oil plug for the first time and the internal threads came out with it. So yes, apparently it has been leaking a little.
I tried pushing in the free wheeling button but I had an extremely difficult time doing so. I then tried starting up the moped again and I did so, but turning that back wheel was very difficult. It finally started up but I had to keep constant gas to it. I noticed that the clutch wasn't spinning when it was ideling, just the variator. I rode it about a block with full throttle and started smelling a burning smell, so I walked it home. Whatever the problem is, I'm not looking forward to it. Anybody have ideas? Gear oil? Clutch? Pulley?
