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(beenin storage since then but started frequently). Just started riding it full time. The exhaust is stock but all battles removed. New jets and shimsput in accordingly to theCalculators. New plugs were installed before riding it full time. Any help would be appreciated
