Get a Pingle petcock, manual one, and a Dan Marc electric cylinder and for get about all the hassle.
I've had my Pingle and Dan Marc going on 4 years now. Two years ago I put in a hidden switch so no one can really steal the old boy. You no throw the switch within 1 1/2 miles, you is a walking or a runnin trying to keep from getting caught stealin.
I turn it to the off position when I park it for the winter and turn it back on in the spring. Only reason for that is so the little ball doesn't get stuck. I might add, I assume it has a ball, I've never had it apart to have a look see.
Honda screwed up not putting a Pingle on it from the factory, BUT, if nothing fails, day don't get no revenue from parts. Parts & service is where the stealer makes his $$$$$ and the factory makes a little $$$$$ selling bikes to stealers to resell and parts they need to order.
Really, Pingle is the very best way to go.
