Removing ca emission equip

Broke my subframe and performing a complete tear down.
Everything was groovy as I pulled parts off the bike and then stored the fasteners on the new subframe...until I hit the CA emissions stuff. The new subframe does not have the canister hangers.

Oh well, I figure I'll just convert mine over to a 49 state model. Problem is, I'm not sure what all to do and if this will effect performance if I screw up.

Things I have noticed
1. my fuel tank has 2 vents, 49 state models have 1. Figure I'll put a plug on mine.
2. My air box has a crudely installed(care of factory) vapor hose that leads to the CA filter I intend on removing. Figure I will glue it shut after removing the hose.

3. There are various lesser hoses leading from the CA filter back to the bike yet to be figured out.

My question... Is there anything online to guide me on this? Are there any pitfalls to avoid (besides the legal one)?

This is my first wrenching experience on a bike. It's pretty simple so far and I have stripped her down completely in prep for the subframe install already. The emissions stuff is a little beyond my comprehension right now though.

Thanks for any help.

The Gen 2 bikes have two sets of emissions stuff. There's the evap system, which you've pretty well described. I think there is a set on instructions for removing it over on the marknet site. It's all pretty straight forward; track back hoses to whatever they hook to, unhook them and put a cap on whatever they hooked to. Don't permanently screw up anything you can't alter unscrew. I found that the big vent hose that comes off the air box, right by the battery, can be pulled from the elbow and the elbow plugged with a medium sized vacuum cap stuck in backwards.

The other emissions related stuff is the air pump. that you should leave intact unless you've installed an after market muffler, as the air injection keeps the catalytic converter happy. If the cat gets unhappy I suppose it might disintegrate and that might choke up your exhaust.

If you need more details, say so. I can do pics of stuff.

Thanks for the advice. I used your tip on plugging the airbox and made sense of the evap stuff thanks to the site you referenced. All is good now.

I'm going to leave the air pump for now, as I run factory exhaust. I did stumble across this describing how to plug it if anyone is interested...

Yes, I made a similar part from a bit of steel plate. He went the extra step and made a plug for the ID of the o-ring, which is a really nice job.
