So, one of my best customers came in with a problem. His son sank his YZ250F in 3 feet of mud, and it took 20 minutes to pull the bike out. After the bike was pulled from the mud, the kid (great kid, didn't know better) started the motor and rode off. Obviously, it died in 10 seconds and won't restart. The motor is FULL of mud. Bottom end has 2 pounds of mud in it, valves, head, carb is full of mud. Oil lines are full of mud. BUT, the cooling system drained perfect Engine Ice! Wooohoo! Would YOU rebuild this 2004? Or buy a $1400 ebay motor?
