I was out riding my 93' yz250 yesterday, all was well I had been riding for about an hour, then it just makes a weird knocking noise all of the sudden so I let off the throttle, and it just dies. It was running great right before this. It almost sounds like a diesel or something. And it will start but it won't idle, its like its having some resistance or something. I did have plenty of coolant and it had good oil and gas. Is it the topend going out? Thanks for the help, I'm new to this stuff.
