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. I fabricated a jig to press the cam gear back on. The jig is necessary because the shaft has no splines or keyways to accurately locate the gear. It is a very simple jig using scraps laying around. I scribed accurate lines on the cam and gear before disassembly and after reassembly they looked to be in perfect alignment. Bikes runs perfect again.
Moral of the story for me is to add replacing the cam bearings at the 7,500 mile interval.
I am firm believer in preventative maintenance.
Rotella synthetic 5-40 change at 300 to 750 miles
wheel bearings, chain and sprockets every 5,000 miles
I am an ex "A" enduro rider 57 years old. I ride the bike fairly hard and try not to abuse it. I never run it under 5,000 rpm so as not to lug the motor. I ride 3-4 D37 dual sport rides a year and numerous trail rides. I also ride my Husky to work everyday I can. It is a 8 mile round trip on surface streets with one against the rev limiter merge onto the freeway for two blocks.
