Air filter is a brand new K&N, the spark plug wires and spark plugs are new also.
The more I investigate, the more it points to the belt.
The bike as about 19000 miles.
Here's a few pics. In the first one, Keep in mind my wheel was totally clean. After a 60 miles run, you can see my finger mark on the wheel.
On the second pic, you can see my finger with the residue.
On the third pic, my finger with residue from my pipes.
And last pic, my finger with residue from my belt's threads.
Suddenly, I feel it is belt residue that end-up on my wheel.
Bike has 19000 miles. Should I change the belt even if it looks and feels solid????
Is there a lubrication that I can use to help the belt??
Or am I kidding myself and someone knows what this is???
