Ok so I have the short exhaust vent tube on the stock fuel cap, 2011 FE570S, and I took the check valve ball out of the cap, as recommended here and on other forums,,, When I put it back together I tightened the three screws back to hand tight and I couldnt get the fuel cap to close any longer. I thought maybe I needed to back the screws off a bit, and when I did that the cap would close, but now I could no longer get the cap off,, push button just wouldnt disengage the lock. Is there a secret to this?
