So today was a bad day for me riding. I was out at a dry lake bed and surrounding trails, and as I was headed back to the truck on the lake bed, going around 75mph, my motor decided to sieze itself out of nowhere. My oil was full, as was my coolant, and the motor was cool to the touch within 10 minutes of seizing. Does anyone have any idea on how that happened, and tips for rebuilding? Thanks.
