While doing my valve checks and then some I noticed some carbony varnish in the throttles and a peek through the spark hole looks a bit dirty.
Anyone have any particular remedies they favor for removing carbon and other ick? I've looked at the Sea Foam spray

Any FHE with it? Or similar products?
Techron carbon cleaner works well.
No fhe with the seafoam products, but they have good reviews.
One issue is there's some build up in the throttle bodies - if the techron in mixed with the gas, would it get at that? The Sea Foam spray is sprayed into the intake system to clear some of that up... in theory
I have used both the Seafoam liquid and aerosol (Deep Creep). They do work in my opinion. I would suggest doing both at the same time.
Here is a procedure used for Outboards that I have similarly used on the duc:

I would think that the same spit back that caused the varnishing/carbon build up in the first place would also rectify the condition.

Isn't Deep Creep their penetrating lube? - I see in the video they due use it to clean a TB on the bench - but I was looking at the Sea Foam Spray for down the gullet since my TBs are still quite in place.

And yeah, I was planning to used 44k or the liquid in the gas at the same time too.

Yeah, you're right. Sea Foam spray is new, the Deep Creep has been around. I have used the deep creep right down the intake like the spray.
for my old carbed monster, i used to pour it right down the carb and it would process it imediately.
for the new EFI bikes the bike would instantly stall when i poured it down the TB. Im not sure where the differences lies. maybe its the difference in motor (DS for single plug)?
I usually clean TBs by using a rag and a bit of carb cleaner and wipe them clean. I normally don't worry about carbon otherwise in a bike motor. On high mileage cages I've done the full BG service (I think might not be available except through shops/dealerships - I was an auto tech at the time). The system includes a gizmo to slowly meter the cleaner into the engine via a vacuum port, a can of spray cleaner that you use to wipe clean the TB and then spray the rest into them intake while the engine is running and then its all topped off with a can of 44k in the tank. Works pretty well.
On a bike I might wonder whether getting rid of the carbon is worth the extra stress and wear of running the cleaners though the motors. If you do go for the cleaners change oil after as it will probably be diluted with the cleaner.
Yeah, the BG induction stuff really isn't an option due to the need for all sorts of special gear which might not be available to mortals and way to costly to be accessible for shade-tree work on mine, and only a couple other bikes.
I wiped out the TB above the butterfly - it's just down on the other side I'm hoping to suss out.
