Just an FYI currently the feds are 2 years behind California. California got new rega in 2006 and 2008. The 2006 Cali regs went federal in 2008 and the 2008 Cali regs will go federal in 2010. These sets of changes are primarily evaporative in nature. Stopping the gas that evaporates 24/7/365 whether the bike is ridden or not.
