The tank has a breather of some sort on the bottom and the cap is "special" California only.
The tube that comes off of the tank breather goes to the charcoal canister in stock configuration. I think these "special" parts were only on the late model California only bike.
On my other Cal bike I have tie wrapped a piece of foam on to the end of the tube and it has always worked fine.
I would like to change the cap parts from the plastic cap to the aluminum one.
Will the cap work properly when the parts are transferred over?
Is there a way to convert the tank to a normal tank? Just cap off the breather or the breather hole?
