Swapped filter(s), changed oil and almost lost the inner sump plug but i recovered it fortunately.
While I was wiping down the tank and the area around it, I noticed there was dirt collecting underneath the gas tank cap bracket. So I took it off and found a bunch around the mouth of the tank.
Before this I swapped chain and sprockets.
Wheel bearings are due any time as a CYA, don't have tools for it yet.
When you service your filter, be sure to clean around the mouth of the gas cap under the bracket, it traps dirt in and your gas cap threads on the tank are prone to rusting.
