GL 1800 Exhaust Question

[gliskey]

I have a 2001 GL 1800 with 32k miles. The bike runs flawlessly, but I noticed that one of the three tubes at the end of the exhaust is considerably darker than the other two.

The top tube is very dark which indicates a rich condition and the bottom two holes are a light gray, lean ?

Anybody know anything about this. Please tell me I don't need to worry, even if I should......... Yikes.

Also, what is the average mileage the valves need to be adjusted. I have heard many different answers and Honda wants $600. for the procedure. Motor sounds fine, no tappet noise at all. Again, bike is at 32 k miles.

Thanks for a great site !

Only one hole on each size is functional,the other two are just for show.

I was gonna write if it runs fine and gets decent fuel mileage with its' regular routine maintenance done don't be looking for a problem.
