My 2006 TE250 turned 10,000 miles a couple of months back. At 7,500 miles I replaced the piston, connecting rod, and main crank bearings. I was on the fence about the crank, I read about a few failures. The crank bearings felt good and I might not replace them at 15,000 miles.
Here is the reason for this report, during an organized dual sport ride a camshaft bearing catastrophically failed. The motor died with a loud clank. Pulled the valve cover off and found one bearing missing all of it's balls. I disassembeld the motor and found all of the balls and no other damage. The cam gear is pressed onto the cam after the bearing. Husky only sells complete cams for about $300US each. Being a mechanic all my life i wasn't spending $600 on cams when they only needed $16 in bearings....
