In my quest to figure out my low mileage issue, I removed the K&N, (just cleaned and oiled last week. Removed carb, cleaned and documented a 48 pilot and 180 main jet. Bowl was spotless. While carb is off, looked at intake, aluminum, looked to be oily/damp where it meets jugs. So, hey, i'm this far, may as well replace intake gaskets.
Once i removed the intake, i looked at the tops of the intake valves with flashlight.....nasty crud buildup.
What causes this? Too rich? Is there a way to clean them without further disassembly?
I'd like to put all back together and just run a couple doses of seafoam. Will that do the trick? Thanks

Oh, no windshield, tires are good psi, brakes are not dragging and no parachute!!

You could use some carb cleaner, and then using a strong stream of air, blow all the crud out the exhaust pipe . Make sure all the valves are closed before you start . :)

Yes may try that. Thanks.
The bigger question is why is it there?

I have the Kuraken hypercharger, that sucks the crankcase/head vapors directly into carb. I guess that would allow it
