The CA model uses a vapor recycler and 49 state ones don't. The simplest fix is rather easy. Replace the gas cap with a 49 state model (vented) or... I can supply an alternative later. No time now, I'm at work.

I recently bought a used tank in very nice condition to replace my battered and peeling one. Unfortunately, I didn't realize the differences between the CA and non-CA models. My old tank has an extra outlet for the CA emissions setup; the new one doesn't. I went ahead and installed it. It runs...sort of. What has started happening is that after running for a time gas stops getting to the engine, and it stops. I noticed that when I open the gas cap on this tank, there's a release of vacuum which never used to happen with the old tank. I can get the bike running again by opening up the tank, releasing the vacuum, and waiting a bit. Choke helps; if I open the choke a bit and am careful to not give the bike too much gas, it keeps running. I'm assuming the differences between the CA and non-CA setups are causing this to happen. Ideally I'd find a CA tank, but it took me so long to find this one (shipped from Ohio) that I don't see that happening without buying a new OEM park. My questions are, 1) Are there any modifications or adjustments to the bike that I could make to get this working reasonably? 2) Does it sound like any other problem, rather than one with the CA/ non-CA differences?
