took a butchers at the air filter as a few suggested looking at it if its feeling a bit lumpy at constant low revs when cruising at 30 -40mph...
i know what a brand new one looks like but what signs are there for a new one needed?
also in the airfilter box there was small traces of what i can only guess at been oil. is this normal?
another thing,, what is the clear resvior type plastic thing in there with a tube going in, a tube coming out and an open hole in?
