Hello, Well I was going like 90 mph on the highway the other day and my drive chain snapped some how and destroyed my airbox and nearly ruined my rear shock. That's no problem. Found the airbox on ebay and I fixed the shock myself. I put it all back together last night and now it WON'T start. The chain did bind the motor and stalled it at high speed. Does anyone think the motor may have jumped it's timing? It's getting fuel and fire. The valves are opening and closing so the timing chain is still together. No blown fuses. Please help me.
