I was recently riding my 2008 Yamaha Raptor 250 when I hit a huge bump and flew off of it. The bike then proceeded to go into the woods and get caught in our neighbors barb wire fence. It was standing on the edge of a huge drop off where coal used to be mined. I couldn't get to it to turn off the gas. It stood on its rear wheels and grab bar for about an hour until I could pull it out with my truck. I let it set for about a day and when I started it and took a small drive, it started smoking out of the exhaust and skipping like it was out of gas. I checked and it was still full of gas. I then parked it and checked the oil and it was rather low. What are your suggestions?
