Hawk Talk

[enforcer89]

So I got my hawk off Craigslist today . Rode it all day then opened the gas cap .it released a lot of pressure when I opened it like it had a vacuum on it . Later maybe 2-3 hours I took it for a short ride it started acting weird like I wasn't getting any fuel . Pushed it all the way home battery went dead from cranking and it wouldn't kick over . I could smell fuel also . Once I got home I jumped it no luck . I opened the gas cap again and closed it back and it fired right up . I didn't try and ride it again but it acted normal. Any ideas ? It's bone stock only thing I've done is changed oil and took off the spark arrester
