i have a cali bike which i removed the carb and canister and got a standard tk carb to replace it. i live in ct so i dont have issues like in cali as far as emisions and all that stuff. so if i dont have a vented gas cap on a cali tank how does the tank vent? just wondering if i should look out for posible problems in the future. my nephew in cali bought a beat to crap tdub and needed the carb so i hooked him up. i have not had any problems yet and when i do remove the gas cap there is no hissing when i crack it open.
