Hi: Yes, I disconnected the rubber hose from the rollover valve and the other end at the tanks vent tube. The whole rubber hose was clear even with an air compressor. Also, I ended up cutting off the 1st 1/4 inch of the metal vent tube, and straightened it out, and drilled the hole twice the size as the normal stock hole, and deep enough, but not so deep that I'd come through the bottom part of the tank, and all this did not cure getting air into my tank. I even had the gas cap off and blew a compressor 100 psi through it with no results. So, I modded the gas cap as Tazman recommended. Today however, I had to replace just one of the rubber plugs in the gas cap because after filling up, and swinging the bike to an upward position, I started to have gas loss through the cap. Now I'm thinking...ok, instead of implosion, I'll have explosion...LOL...So by replacing just one rubber plug in the largest of both holes in the gas cap, it rectified the problem...No more spillage. I only fill my tank to the bottom of the neck anyways, but that's all it took swinging the bike up to have gas come out, and almost on my pipes.
