'08 CA Charcoal Canister

[RadioHowie]

Ok, so can someone explain what the "rollover valve" is and what it does? :huh:

I've got this one, guys.....

It's the valve that triggers when you finish sweating on your wife/girlfriend and rollover to go to sleep. It fires off and makes your partner want to "cuddle".

That's why it should be removed immediately!!

Is it just me and my computer disfunction? I cannot find a write up about removing the charcoal canister. Maybe it's just so easy no write up is necessary? Like unplug the in and out hoses and connect togather. A little help please. Thanks

I made notes!

I took hose #5 (from tank to the top of the rollover valve) and disconnected it at the top of the rollover valve to let it vent.

Then I removed hose #4 (tank to canister direct) from the canister and plugged it. The canister, although still there, is now out of the picture.

The only difference between doing this and the 49 state version is that the vent hose is terminating behind the fairing underneath the radiator (still at the bottom) instead of down through the center of the bike. The overflow hose exits at the same place on both models and there isn't enough vapor exiting the vent hose for there to be a problem with the different vent hose routings. The 49 state routing tees the 2 hoses together.

Also, the 49 state version either doesn't have the ports in the bottom of the #1 & #4 throttle bodies, or they are plugged. Doesn't matter because the throttle body ports are plugged when the # 5 hose is plugged so the throttle bodies won't suck air through the ports.

If you really wanted to you could either add the T, or reroute the vent hose next to the overflow hose, but I don't see the point.

Am planning to add the tee on my 07 ca, just cut the hoses above the leftside crankcase cover. Your post has me worried tho, sounds like I will be sucking some air into the throttle bodies. Is that why there is a check valve on the canister? Should I be pluging one hose and running the other thru the belly pan? Or plugging the throttle bodies? Or replacing the check valve above the tee? I did find a diagram in this post however maybe someone could shed some light on this.link

In that post the diagram listed is identical to what I have, however the hose item numbers are different, probably because it's from an older manual.

So, in that diagram hose # 47 is removed from the rollover valve and plugged, and hose # 48 is disconnected and allowed to vent. Only difference is that you have 2 completely separate hoses, one for the vent and one for the overflow. You don't need the T. The method I described accomplishes the same thing.

Anyways...back on topic. I guess what I am trying to find out is if the tee method will work without issue's, just seems a cleaner way of handling it. In looking at the throttle body sketch one can clearly see the cal version has hoses connected to the air filter box but if they are connected to the throttle body it is unclear. And in looking at the fuel tank sketch it looks as though both tubes go directly the tank. One for overflow and one for venting at the gas cap. If someone could add some clairity or has a sketch of the cal cable routing that would be greatly appricated. Thanks

Ok so I did the tee method and haven't seen any adverse effects. Also there doesn't appear to be any sucking of air at least not at idle. I will continue to run the bike as is and will investigate whether any hoses are connected to the throttle bodies the next time I have the tank off.

Any updates on this? So is there a tube that goes to the throttle bodies that needs plugged? The diagram doesn't show that. If so, how do you plug it? Does anyone have a part number?

I bought the tee and need to figure out how to make this happen before my MSF course next week. Don't want the bike stumbling all day long during the short rides...
