On the non CA. models the two lines exiting from under the tank extend down the left front down tube and end just below the crankcase, one of these lines has a check (tipover) valve and is a vent for the tank, the other is an overflow and has no valve. One of the ports at the rear throttle body(left side on the bike) has a nipple on it, this is the port you have to block off on the CA. bikes. Now my question is, on the CA. bikes do all these (3)lines end at the cannister? I've never actually looked close enough at it to see this.
