hi there, im thinking about buying a new air filter for the GS and i have noticed the air box and filter are hidden beneath the petrol tank and facing the wrong way, is there any way that i can get forced induction maybe? or some kind of new box/ filter? thanks sean
You could put in a free flowing airfilter such as a K&N. If you do this then you will need to change the jets as the bike will then run lean which will make the engine run hotter (and better for a while) and could lead to you holing a piston.
I found these 2 sites which give you the jet and carb setttings for free flowing airfilters and show you how its done.
