Vortex keyless fuel cap.

I have a vortex fuel cap on my 89 750, I have been reading that these caps are not vented properly and can cause running issues. My bike after running for a while starts running extremely poor. Then after being parked for a bit, I noticed fuel leaks up around the cap base and down the tank, is this an issue of improper venting?

Absolutely could be. Vac in the tank slows fuel delivery, excessive pressure in the tank will cause strange fuel leaks. I can't remember what I did to mine. I'll have to pry around and try to remember.

Thank you, I have read so much about venting issues with these caps and modifying the Allen screw/spring/ball to remedy the issue

Trying to remember what I did with mine... Believe I removed the spring, possibly both spring and the ball and mine worked great. Been too many years and too many drinks since then.

Thank you so much, I was thinking about doing that
