The other one is super cracked too.

If you haven't already, we need to future proof your forks - every single SSS forks will have the free Pistons fail in them eventually.

Mine have been replaced with Aluminum? cups by motoexperts.

My last Yamaha had this failure under 100 hrs. My brothers did the same.

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.

My WR450 would tow my Cummins and get 50 mpg while doing it.

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.

Six gears and a plate is all it’s gonna take Yamaha

Edit: oh and not 400lbs!

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.

How the heck is the chain cutting a groove like that?

That is my question I am trying to get answered. Cam chain is tight and the sliders are solidly in place.

Must be a Yamaha thing 🍆🍢🤷‍♂️

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.
