Scooter stopped running

[Darn8]

Well, as far as how attached I am to the scooter, I need it since it's my primary source of transportation. I'm pretty at working on mechanical things so I know I am capable of doing the work myself. I guess my Makin question is, will replacing the top end fix the problem or do you guys think it could be something else?

I'll admit I've been absent when it comes to maintaining it, I've done a couple of oil changes but that's it. I realize now that there's more to it than that to keep it running good.
