I'd like to remove all the emissions crap from my California-spec GPZ. What to do, apart from ripping out all non-essential looking hoses?

There's a charcoal canister, separator and vacuum valve that all need to be removed along with all the hoses. The reed valves in the valve cover need to be blocked off. There are several ways to do it. Buy some trick block off plates from Muzzy, pull the hoses off and plug the two holes or the simplest method, just connect the two hoses together. The carb rack has 4 vacuum taps, one at each carb. After removing all the emission crap, the only connection here is for the petcock. Make sure the other three taps are capped off. There's also an extra vent on the gas tank that you should cap as well. A Stage 1 jet kit would be in order when switching to pods with a stock exhaust, buy a Factory kit please. The good K&N individual filters for our bike will cost about $100 + shipping from Parts411. The K&N part number is RC-0984 for a set of 4 filters.
