Hi all, need a bit of help. Not had my classic long, noticed a random vacuum hose not attached earlier. Its a MY98 and has a K&N on it (before anyone says it yes i know standard airbox is better, was like this when i bought it, will be getting standard for it). Hose goes to a wee pipe that goes under inlet manifold. Should it be blanked off cause of induction kit or where should it be attached? As said will be getting standard air box for it but just want to know what to do with this for now. Sorry for crap pics Cheers
