Okay guys, so here's my current dilemma at 3800 miles.
About three weeks ago I was on my way home and lost my exhaust nuts. This was after a couple weeks of noticing a metallic rattle/clinking noise that I would come to realize was the noise of my exhaust shaking more and more as the nuts holding it on slowly shook more and more loose.
So I replaced those nuts and everything has been good up until today. I was taking a quick scoot to the post office right up the street and I got some serious bogging and stuttering while I was riding. It also has stalled on me both times I took it out for a run to try to replicate the problem. It stalls after the stuttering and bucking happens and I get back on the throttle. Got back to the house and did some inspection. My results led me to find that
A) I have exhaust leaking out at the head, enough to blow around sand and leaves on the ground beneath the scoot, but not a crazy amount. I believe I must have lost my gasket when I lost my nuts (heh) and not realized it. Otherwise the stock gasket is just no longer suitable. Either way I have ordered a new gasket.
B) Upon inspecting my CVT I realized that the belt has a bit of a slappy/floppy thing going on when I let off the throttle and decelerate, probably right around 2k RPM is when it happens. There is also a nice coating of black powder in the CVT cover, and I just cleaned it all out completely about two weeks ago. The belt itself makes a little bit of noise when this happens but nothing too alarming sounding.The belt also is showing metal through the rubber on the side facing the CVT cover as well as in a line on the flat side of the belt. Either way I also plan on replacing the belt this week as I suspect the stock belt is reaching its end and these are all signs of this. Would I be correct in this assumption?
As best as I could tell I don't have any air or fuel leaks, and she still starts just fine. If there's anything anyone can add or suggest to check out I'm more than open to suggestions since I've got nothing but time this weekend to sort it out.

% positive it's nothing crazy at least.
