Hey all, I have a 1998 GPX250. When the fuel is getting low in the tank, after I stop I can hear a whistling sort of sound coming from the fuel cap. I open the fuel cap and hear the "whoosh" that I've heard about so much. So on the weekend while I was doing service on the bike I thought I'd have a look at the breather as well. Well as you may have guessed... I couldn't find the breather pipe. Where is it? I have the owners manual and the service manual and I just could find it. Any help/advice would much appreciated, thanks.
