just took my airbox off my spada, and am thinking about using pod filters... it just so happens i have 2 filters, presumadly off a dirtbike/small car, about the size of a soup can (x2) they are foam, probably washable and need to be oiled... -what are the pros/cons of pod filters? do they add performance if coupled to my racing exhaust? -will they increase engine wear? -do the connecting tubes (carby to filter) need to be the same length, or will tuning the carbs eliminate the difference? -will riding in the wet be a problem? -should i get the carbs tuned or do anthing else to the bike ounce done, and will it damage the bike if not tuned?
