S&S will have a new air-cleaner kit for its' E&G carburetors that will do away with the charcoal canisters on Calif. bikes. It has a sealed nickel plated aluminum rotary valve that seals against a black anodized plate to meet the evaporative hydrocarbon emission levels mandated by ARB with out any loss of performance. It seals when the motor is shut down. I'm not sure exactly how it works but more information can be found at
www.sscycle.com. It looks like S&S is on the ball. S&S says it will be available in March of 08, part # 106-1449
