Howdy,
I just had the valves inspected on my 2000 blackbird. Again they needed no adjustment and I asked why not. He said riding this bike at average speeds or even higher than average dosnt really wear on this motor. kicking it up to 10,000 rpms on a regular basis that will affect it but as we all know these things are missles above 7,000 rpm,s . In fact that with 36,000 miles on my bike it still has not had any shims added or replaced just a little fyi for you folks. He said to bring it back to get it checked at 50k so we will see what it needs then.
