OK, so i was trail riding my cr85 for a while yesterday. I was in 5th gear down the road, and i went to give it more gas to keep up with my friends, and my bike basically shut off, kinda like locked up. I pulled in the clutch and rolled to a stop. I thought i was just out of gas, but i filled it up, changed the spark plug, cleaned the air filter, and it wont start. Ive tried roll starting it, everyway possible to start it. Did my top end blow? What else might the problem be before i spend $100 on a top end.
When i try kick starting it, it does absolutley nothing, when i try roll starting it, you can hear it starting for a second but then shutting right off.
