Excessive Intake Valve Carbon...Causes?

I'm in the middle of a good tune up on the ol' Gix. Bike has just a tick under 16,000 miles. I've pulled throttle boddies and valve cover, checked the lash, which is right in speck, .150mm on the intake and .250 on the exhaust when cold at TDC for that cyl. on all 4. Plugs look as they should, maby a little brake clean and wire brush, gaps were slightly off. My big concern is the amount of carbon build up on the outside of the intake valves. It's pretty FN thick. I may take some pics if needs. Is this normal? I've always been easy on the bike and I think that may be the issue..just never really getting a chance to air it out. The other thing is 99% of the miles on the bike were put on in Phoenix, AZ were 91 octain is the best gas you can get at the pumps....Rat IMO. Most rides are to and from work, and the standard weekend jaunt so would you guys consider this build-up normal? Any ideas?

Bike(s):
lots of em






cheap gas and very rich, pipe will have soot as well, just not as much.
Gotta open it up once in a while to blow the carbon out, not 100+ mph, just stretch the rpm's out in the early gears every once in a while to keep it purged and cleaner. check tune .
