Gas cap leaking gas

Oh and by the way, I guess the tank was painted when I bought it and the rim of the hole for the cap has uneven paint on it. Should it be cleaned and even?
Can I go to any motorcycle shop to buy the seal for the cap or are the seals all different sizes?

The same cap is used on the KZ1000MKII and I have over 80,000 miles with that piece of junk. (Cap, not motorcycle).
I bought mine the cap would leak if the tank was more than 3/4 full if I rode hard, so I replaced the seal. Did not help, so I replace the entire cap with a new Kawasaki cap. Did not help. Also replaced the seals on the screws and even sealed the screws themselves to insure leak was from the cap and not the mounts. So since then it's been my contention that the design of this cap is the craps. I just came to the realization to never park the motorcycle in the sun with more than 3/4 tank, never ride hard with more than 3/4 tank. Do these and it will leak every time. Even doing these precautions the cap design just leaks if gas is near it. Even vapors coming out of it will liquify and you'll drip gas down the tank, or stranger yet you'll leak up the tank. I've actually parked on the sidestand and come out to find gas leaking up from the right end of the cap leaking uphill. So I'm all ears too as to whether anyone else finds this cap works without leaks.
321,000 miles on KZ's that I can remember. Not going to see any more.

I noticed today after I came from my ride that there was gas leaking from the cap of the gas tank. And I could hear a hissing noise from it like there is either air going in or coming out. I was thinking it might be the seal, but I checked it and it looked ok. Who knows though, I do not know what is a good seal or bad seal. And about the noise I hear, could someone tell me what that might be?

The guy who painted my tank left the orings out when he put the cap assembly back on. I replaced the seal first and it didnt help at all but the orings took care of the problem altogether.

my 74 's gas cap leaks the same so i only fill it to about 3/4 full and fuel up more often not a problem for me. but i tend to ignore the little things
Caused a double-take from my aging memory bank when all the big Harleys were "74's" :laugh:
