I have wear from the chain on the top of my swingarm, not the wear guards, but on the swingarm itself. anyone else getting this? my chain is adjusted in spec, and i dont understand why its hitting the swingarm.
Definitely a tension issue. When you are using the engine brake during deceleration, tension on the chain is reversed (tension is felt below the swing arm) and any slack will droop above the swing arm. This will cause the marks you are seeing.
