Smog Cannister Removal (How to)

Recommended Posts

For California SM models....(I think S models too ??)

Once I took this stupid cannister out, I realized how easy it was and what a problem it was causing.

As Most of us know...when you overfill your gas tank...raw gas is being drawn to your smog cannister (On ALL California bikes) and is causing the bike to act as if it were out of gas. Next...you'll get it started and then it will run fine for a mile or two and then die again. Well...this little cannister is your problem! :bonk: For all those that need help on removing it....here is a "master post" if you will (mimicking Burned's 3X3 post) :D:prof: ...Along the way are a few pics I hope helped out...let me know it I missed anything or if you need a better shot.

Okay, first order of business...unbolt that ugly black/greyish cannister from under the rear left area of the sub-frame. There will be two lines running to the front of the bike.

The line with the black wrap around it (also has a red stripe on it) goes to the fuel shut-off valve. Take this line completly out including the fuel shut-off valve.

The other line goes to the carb. Follow this line to that carb and remove it all. Cap the nipple on the carb where that line went.

Heres the angle at the fuel shut-off valve

The line that is cut in this picture is the line that goes up to the in-tank vent valve. This line needs to be routed under the bike (preferably under the swingarm like most dirtbikes).

If you need a vacuum diagram...look on the frame on the left side...

Thats it people! Now that line that runs from the petcock to the carb....leave that in and your petcock will function normally (leave it on "ON"). You wont have to fidget with that being on the "PRI" position. The owners manual actually says to NEVER leave it on PRI anyway.

Let me know if this helps...now theres a good post someone can look at to remove that pesky thing!! Ride safe everyone! :prof::applause:

Thanks Kenrock this is very helpful. Like i said earlier, i spent an hour yesterday searching through the TT forums on how to do this. Only if you had posted this one day earlier you could have saved me 55 minutes. :D This is the best post I have seen on this subject and with your pics it makes it very clear. I guess I know what I'll be doing tomorrow night. :applause: Thanks again. ...chris...

PS. What do you think is the best method of plugging the nipple on the carb?

I just left about an inch and a half of the hose/tubing on the nipple, then plugged that with an oversized flat screw and cinched it with a zip-tie.

BTW, nice "how-to" Kenrock :applause:

I just used a vacuum cap I had laying around off an old carb from my 64 Impala :D . You can get an assortment of caps at your local Kragen ot Autozone. :applause:

I just got done yanking the canister off of my 06 400sm and have a couple suggestions...

I used the vacuum cap off of the canister to plug the carb.

I used one of the lines going to the canister in place of the one from the tank. It was a little longer so I could hang it down past the swing arm.

total time ~30 minutes.

Hi Ken,:excuseme:

Thanks for taking the time to post such a clear helpful article. I just finished following your excellently written instructions, and haven't run the bike yet because it was dark by the time I finished, but all went well...

It's sooo satisfying to remove all of that crap! :thumbsdn:

You da man! :devil:

Take Care,

Greg

NOW MAKE KEN'S ARTICLE A STICKY!!!!!!!!!!! :thumbsdn:

So...I know this is recommended...part of the derestriction...but &%$#@! does this mod actually do? Is there any performance benefit from this? I suppose there is some weight savings and it tidy's the rear up a bit...is that it? Is there ANY benefit to the Carbon Canister?

TIA :mad: :mad:

Yeah,of course.Next time you lay your bike down and fuel floods your canister,you won't have to worry about it flooding the canister.You'll be able to start your bike right away and drive off.Instead of being stranded for a long time.How's that?

Not only does removing the PAIR canister +hosage save you 631 grams, but it also gives you a nice supply kit of hoses, clamps, zip-ties, couplers, bolts. :mad:

The fuel shutoff valve :mad: mounts onto a bracket for that purpose. It's easier to remove the whole bracket from the heatsink (1 bolt) than to remove those two stubborn philips screws.

I found the surplus nipple-cover on the canister to be Too Large to fit tightly on the carb tap. Even with a clamp, it would probably leak.

One of the removed hoses is also the perfect length to go from the tank to the rear swingarm. Bonus!
