Everyone,
While taking my exhaust off to do some other repairs I happened to look into the exhaust port on the heads and noticed the exhaust valves seemed to have some kind of white residue on them.
Just curious if this sounds familiar with anyone?
Some background history on the bike.
2004 America with only 2k miles (been in storage since then but started frequently).
Just started riding it full time.
The exhaust is stock but all battles removed.
New jets and shims put in accordingly to the Calculators.
New plugs were installed before riding it full time.
Any help would be appreciated.

Ok it is usually the black build up (exhaust carbon) burn till it turns white.
I have no faith in human perfectability. I think that human exertion will have no appreciable effect upon humanity. Man is now only more active - not more happy - nor more wise, than he was 6000 years ago.

Probably an indication of being slightly lean.

Nothing wrong with the exhaust valves being white.
