So I'm still learning a lot about my Vulcan. I realized mine has a Caddman mod and air filter on the right side with the ICS removed. I opened up the left side and was greeted with a bunch of orange foamy junk and a very dirty air filter. Is this mold or some sort of spray on foam? It looks like some made its way into the central air passage to the right side of the bike. Is this a problem?
Looks like the air filter used foam on top and bottom as gasket material and it's falling apart. I'd clean all the that out and get a new filter to put in there.
It looks like the previous owner did a half Caddman mod. I'm gonna mod the left side and put a stronger resistor in line. The bikes been running too lean as it is and there's only a 330 ohm in there.
Unfortunately, il looks as though you have been sucking that crap right into your intake and cylinders. You might check your throttle body to see if it's got any of that gunk in there.
As crazyriderguy suggests the residue looks like disintegrating air filter material. I had a somewhat similar situation with a Yamaha but fortunately none of the material got into the engine intake. The disintegrating Yamaha filter material had a very similar color to that in the pics.
This past summer I found the same orange foam crumbling from the air filter on my 98 1500. It was the original factory air cleaner element that just rotted out. It had made it's way to the crossover and the dog bowl on the right side...
I was in there to clean the carb and figured this contributed to the no start condition I was working on. As it happens, the carb did need a good cleaning, however none of the orange foam was evident in the carb or the intakes to the engine.
I used a combination of a shop vac and a compressor to get that out of the crossover...
