Do people really say that Yamahas are not known for failures? I've only owned one, and I had zero trouble with it, but I know a ton of guys with the exact same bike who lost 3rd gear.

Jeeper mostly likes to harass Gravy and I about our superior Austrian bikes which is really just a way for him to hide behind his façade of being cheap. It makes him feel better about claiming poverty while owning multiple ARB fridges. We mostly let him get away with it because he is a great dude and Yamaha's are a close 2nd to Orange bikes.

I have never had a wear problem on KTM cam chain sliders but this is the second set with odd wear that shows up as plastic shavings in the oil screen.


BTW……not the same motor. One was the practice bike I rebuilt in January and these are out of the race bike.

I had an XR400 eat a slider like that. Locked up from lack of oil. One of the links of the cam chain broke in the middle. Acted like a shark fin, tore it up, and clogged the oil screen.

The Yamaha cam chains are a known weak point in the motor. I will look closed at the chain I just took out. The race team owner spoke to a former factory Kawi mechanic and showed him the pictures and he confirmed that it is a bad cam chain. He strongly recommended to start using a Pro-X cam chain and not the OEM.
