Desmog CA EVAP, PAIR Valves...

[djdiscman]

I have a California Model Fury. This past weekend I removed all the CA EVAP emissions stuff and the PAIR valves.

For the EVAP job, I used a 1/8" rubber vacuum cap (you can get at any auto-parts store) to cap the vacuum hose outlet on the throttle body. I disconnected the fuel tank breather hose from the EVAP canister and allowed it to hang under the bike. I removed everything else (the EVAP canister, canister hose, Purge Control Solenoid Valve, vacuum hose, air inlet hose) and put it all in a storage box.... in case California decides to start requiring SMOG checks for bikes.

For removing the PAIR valves, I used Biglry & Bone's Block Off Plates from FastCycleParts.com. When I removed the air suction hose from the air box, I used a 1/2" rubber vacuum cap to cap the outlet. I then put the PAIR valves, solenoid valve and hoses into the storage box with the EVAP stuff.... just in case.

This all went very easy on the Fury. You don't even have to remove the fuel tank. I would definitely recommend doing the PAIR valves if you are having any problems with backfiring / popping on deceleration. (The PAIR valves suck air into your exhaust and intentionally cause your bike to backfire).

P.S. - If you want to get Block Off Plates (or anything else) at FastCycleParts.com, you can use COUPON CODE: 11F928098A. It will save you $20 off an order of $100 or more.

IMHO, restricting emissions of unburned Hydrocarbons into the air, via both PAIR air injection to complete combustion, and Canister storage to trap raw vapors are actually good things.

Seriously?

This in relation to the total number of vehicles in the U.S.

I should have put a disclaimer on my posting:

IF YOU CHOSE TO MAKE THESE MODIFICATIONS, AL GORE WILL NOT BE HAPPY WITH YOU!

And if by chance Al Gore calls you from his private jet to tell you how disappointed he is, please remind him that his jet has released more hydrocarbons in the last 10 seconds than your bike will release in its entire life.

Just kidding furious_blue! You are right. We should all try and do our part to clean up the environment. Heck, that might be why some of us are riding a bike in the first place.

What is the point of doing this mod? Do you gain anything?

i second this question. it's irrelevant and does not apply to me. (i'm in ohio) i'm just curious, are there any performance gains? sound differences? you mentioned back firing and popping, was that before or after everything was removed?

There are a few reasons to do these mods. First, the items I removed are completely unnecessary. The factory installs them only for SMOG purposes and they actually make your bike perform worse (the factory would not install these items if the government didn't force them to). Second, the items removed add unnecessary weight to your bike. Third, this mod simplifies the fuel system and exhaust system (less potential problems in the future). Your bike will perform exactly how it is supposed to perform.

I mentioned backfiring / popping on deceleration because I know a lot of Fury owners changed their pipes or drilled out the stock pipes and they created a problem of popping every time they decel. Blocking off the PAIR valves should eliminate any popping they are experiencing.

ryguy00, your bike may not have the EVAP canister, but every bike has PAIR valves. You said in another post that you are looking for the loudest pipes possible. You better block off the PAIR valves when you switch your pipes, or you will get the loudest backfire possible.

i have the fuggin mayhems with fuggin fuel controller. i don't even know where the pair valves would be to block them off but the bike runs great! i CAN make it backfire, but i have to TRY. (do it on purpose) if i'm not trying, it barely even gurgles on decel unless i downshift way too soon. who knows?

Neither of these sytems will have any affect on performance pro or con, iand you will probably save more weight if you leave your phone at home. Removeing the Pair will only help if you have a decel gurggle or popping. As far as the emissions, you guys kill me, you have no problem gutting or junking your catalytic convrter, but don't want to remove the pair ? ROFLMAO
