Okay I went back inside of it to check it out further - still no f'in clue. I tried following the manual to disassemble the casing, but I got stuck, so I decided to just leave it alone before I break something.
Are you or anybody else interested in repair work? I can mail the engine out and pay whatever for somebody to try to fix this issue. I can't spend too terribly much - I paid $63 for the bike itself. But I really want to get this fixed asap! Email me if your interested.
