Emissions Crap

Just to be sure this is all the Emissions stuff right? Making sure I didn’t pull anything important out.

Don't forget to pull off the EGR covers and block the ports. You can toss the covers after.

That looks a bit ugly. Most either make “coasters” which are just flat plates with no valve hole, or the just put a cane tip over the inlet tube.

Some just stuff a marble in the hose.

You can also just use a solid gasket under the stock cover.

Meh. The bike sat outside next to a garage since the early 90's and had 900 miles when I bought it in 2015. Its not going to win any polish and shine contests!

I love your description of this stuff. It is indeed CRAP Instead of coasters to cover up where the PAIR system hoses went, I just left the stock covers there, and capped them with car heater hose fitting caps available at pretty much any auto parts store. I can see using coasters (which do look better) back when these bikes were new, but considering what a lot of people are doing to them now, I really don't see how it matters. Anything looks better than those huge hoses that came on the bike.

This is the EVAP system.https://www.cheapcycleparts.com/oemp...tive-system-ca

These are all parts of the PAIR system, which should be removed.https://www.cheapcycleparts.com/oemp...20/air-cleaner

Remember to cap/plug all holes/fittings left open when these parts are removed.

Also take the gas cap apart and remove everything that you can get out of it.

If you have a CA tank, it will have 2 fittings at the rear, just under the front of the seat. Put rubber hoses on both fittings, and run them down under the bike somewhere. Leave the bottom ends open. This will ensure that you have the tank properly vented to the atmosphere and eliminate the POOGS symptoms caused by inadequate ventilation.

If you want, box up all the parts and send them to the EPA. I threw mine away, but that would have made me feel better.

First thing I did when I bought my 2005 (in 2011) was to peel off that uglifying sticker below the gas cap which says don't fill it to the top. (because the fuel would overflow and end up in the charcoal canister ?) This bike has the CA emission system, and I seem to remember seeing a diagram of the system either on the bike or in a manual. All the emission system components are still intact, and I plan to keep the bike looking mostly stock, and the bike continues to run okay. With the old saying in mind "If it ain't broke don't fix it", is there any major advantage to removing the smog system on this bike ?

My first reason is philosophical. It's GARBAGE that doesn't belong there. Removing it will also get rid of a lot of excess weight and a ridiculous amount of clutter. Like I've said before, if you remove both the PAIR system and EVAP system, it is enough GARBAGE to fill a 5 gallon bucket. Do you really want that CRAP on your bike? If it were a new bike, I could see leaving it there till the warranty expired (but still disabling it), then getting rid of it. You can disable the PAIR system simply by removing the huge ugly hoses from the reed valve covers, plugging them with marbles, and putting the hoses back. You can disable the EVAP system by removing both hoses at the rear of the gas tank, and removing the guts from the gas cap. But you're still hauling around 5 gallons of EPA GARBAGE. Made me feel real good getting rid of it. I have been fighting the EPA since 1975. They are the biggest enemy of any bike or car enthusiast.

Hmmmmmmmmmmmmmmm, isn't it there for a reason? I thought you have always said that engineers put things on a bike for a reason? But in areas you don't agree on, engineers don't know what they are talking about? Like dual front brakes...

I think there was a similar conversation on how dual throttle cables were a waste as well.....

Silly Silly engineers....
