Having a CA model tank is actually a good thing when it comes to tank venting. Once you remove all the emissions crap, you actually have 2 tank vents, and one cannot fail. I ran rubber hoses from both mine, from the back of the tank down under the bike. Some time ago, I looked at another guys Vulcan 750, who was having this poog issue. His was a non CA model, and only had one vent hose fitting. It is vented through that tiny little grommet under the gas cap. Using alcohol gas had caused that to swell up, and cut off air flow. I removed it, and the bike ran fine. But with the CA tank, the other vent has no rubber parts, other than the hose. And guess what? I found the very ends of both my vent hoses (under the bike) all swollen, from using alcohol gas. Found the same thing on the carb vent hoses, and on the external gas cap mounted vent hose on my dirt bike. Not too long after finding the swollen hose on the dirt bike, an '02 XR400 bought used, the plastic gas tank cracked. And it was not from a crash, or sitting out in the sun. The vent hose was open. The alcohol in the gas simply destroyed the genuine Honda gas tank. Alcohol gas is some really bad stuff, and can and will destroy all the plastic and rubber parts in your fuel system. It may take a while, but it will happen. I would avoid using it if at all possible, unfortunately it is the only thing available in my state.
