I use a 7 lb cap right now but I really should put a 4 lb one in.
last spring i was at a show and the gasket on my zero cap crapped out. i couldnt get a 4lb johnny on the spot so i opted for a 7lb to get it home. the button wasnt working and by the time i got home the radiator sprung numerous leaks luckily for be ut was at the top at the tank. since then i got it recored and use a 4lb cap since i could find another zero cap along with the 4lb button.
