Have you found any traces of dirt in the intake tract?

There was some very fine something almost oily in the tube from the air box to the carb but the reeds and other side looked good. I have the SB air box adapter kit as I didn't feel safe with the stock air filter setup. I'd like to find some new clamps for both sides of the carb as I have them as tight as they go and it seems they could be tighter. I've yet to find a new hose clamp to fit the slim groove. I tried a set from a 2nd air box I bought but they are the same. When I power wash it I'm always afraid to blast the carburetor too hard.
