So my bike worked fine for like a week no problems. Then one day my muffler fell off and bout two miles down the road she stalled on me. I tried riding her again that day and she got me about 3 miles and stalled. The guy I bout it off of said it was the carb. So I met up with him he hooked me up with a carb n muffler. Well the new carb I couldn't even get it started. So I put the old one back on fired up no problem road around for several miles and nothing so I figured I was safe. I went to ride her into work one night and got four miles and she stalled again. About a mile down she started up again and got like another three miles before she stalled again. I put a new ngk plug in her thinking that might help cause the stock one looked gnarly. And nothing. But even before the new plug I was only getting around my apt complex which is really small btw. Also even going like 10mph just that one circle around my motor is really hot. I tried the gas cap trick I read on here and nothing I really need some help guys please help me asap cause this girl is my ride to work n back.
