Second time now but at 400 engine hours and 10,000 miles on the clock should I complain?
First time was at 176 engine hours and 4600 miles. Bike was running great but I noticed a drastic increase of little silver hairs on the magnetic drain plug. Some additional investigation found the rollers bearings on the rocker arms had gone kaput. The rolling action was rough/bad. Two new rocker arms later all was well.
Now at 400 engine hours and 10,000 miles it's deja-vu all over again except this time it's only the intake rocker arm roller bearings that went bad. Exhaust roller feels fine. Easy fix, and 'only' a $100 part, this time.
Definitely replacing the intake rocker arm. Kind of debating whether to also replace the exhaust rocker arm as a preventative measure. Photo from 03 bike used for illustration.
