Yeah, so I'm an idiot. That's the first thing you should know.
The other day I was looking at my rear wheel and wondering what this strange mark all the way around it on the right side was. Well, I looked a little closer, and my rear tire was rubbing the swingarm...for weeks.
So I fixed that last night, and bam, I'm back up to the high 30s like I'm supposed to be.
Linda, remember when I said it felt like my rear brake was on sometimes? Yeah, it wasn't the brake, but thank you for the WD40 anyways. haha
I fail at moped mechanics.
