Ok, so yesterday I went riding and at first I would be going pretty fast, riding pretty hard, and all of a sudden it would just cut off, so I had to hold the clutch to stop from slamming on brakes, it did this about 3 times to be exact. Then I was going and there was a tree on the ground I had to cross, so I wheelied up and got over it fine, then it just stopped (it had been making weird noises since I started riding). So then I tried kick starting it, and the kick starter rod would not even go down, it just stuck up. So I tried to start it where you run with it, hold the clutch, put it in first gear, and it would start. But none of these works, and I tried everything I know, I think it might be the pistons though. Please help!
