Last year I fixed a fellas 1993 XR650l that dropped a seat. Took out the piston, the head was so cracked it wasn't worth the repair. Big money fix. Even though he had re-jetted the carb he was running it on the freeway like a CB1000. Then he moved farther from work and blew up the motor again running it so hard. I talked him into a multi cylinder bike.
