Default Help diagnosing please...Pic inside

I'm in the middle of changing out my stock headers to the FM 2/1/2. Upon inspection I found this build up on the the valves.
I'm guessing this is due to a lean condition?
Some help educating please! Other than a new tune from FM for my PV is there anything else I need to do? Thanks!

Ps- the bike has about 7k miles on it.

Ok, did some reading and have a better idea now. It seems this is a normal occurance on the rear cylinder due to heat. I did not post a pic of the front cylinder. I need to take a look when I get home and see how that is.

Default Looks like she needs to be richened out a bit

FM has a great map program available if you bought from them and Dynojet has a huge library of maps for almost every conceivable combo.

Exactly, no need to fret about how the valves look on a relatively stock bike at 7000 miles.
