what is that black box??

[hitman87]

what is that black box on some of the 07 and newer s4r's that sits on the lower radiator hose??? its not on all the bikes but i have seen it on a few... anybody know??

It's the flight recorder. In case of accident the FAA will analyze it to see if it was rider error or not.


Oh come on! You know you were thinking the same thing you just didn't have the nerve to look stupid by posting it! See, I don't have that problem!


I seriously have no idea what it is. Don't have a S4RS but I am sure the answer will be forthcoming.

[hitman87]

its not just on the s4rs.... its on some of the 07 and newer s4r.... but the flight recorder reply was kinda funny...

most likely what you are talking about is the charcoal canister.


It has to do with emissions.


That was the first thing I removed from both my bikes.

thanks cyrus

suuuuure.... had it been a white box...it'd still be on Juds bike.

there should be a secondary hose running to your seat. it hooks to your anus... for those "oh shit" moments...
the bike runs on fear. give it fuel.

I really had to think back to remember that thing.  I completely forgot about that canister.... had the shop remove it right after I got it.

Here is a thread with a tutorial for older Monsters, but most still applies

Yep, emissions canister, for the gas tank specifically.  When the gas gets hot some of it evaporates, since the tank must be vented to allow air into the tank as the gas level falls during use, the evaporated hydrocarbons come out the vent.  The Enviro-Greenies don't like hydrocarbons floating around in the air, so the vent is routed through the charcoal canister.  The charcoal absorbs the hydrocarbons while allowing air to flow in and out of the tank.

I've always wondered: at some point the charcoal in the canister becomes saturated and the canister needs replacement, so, how many moto makers actually stock and sell replacement canisters?  I know they must have some stock, but who really has a NEED to replace a canister that most everyone tosses in the garbage?  At what levels to manufactuers stock/ship replacements?

I await the day some government environmental agency scrutinizes the records of moto makers to see if this is being done.  Sounds crazy I know.  However, a few years ago I did see one of those flashing road signs on La Cienega in LA announcing, "Modified Exhaust Check Point Ahead", and I thought THAT was crazy too.

that's where the other tubes come into play. the intake plenums suck the gas vapors out of the canister.

Jesus, NOOOOO Dont take that off!!!

It hold the flux capacitor! 88 mph!!!

Ok, kidding.. its the charcoal canister... Remove the lines all the way to the bottom of the tank and leave it open to air.

Seriously though, do NOT take off that canister.  It's the only thing keeping the plastic tank from swelling.

does that year monster also have the tubes to the intake plenums? he'll need to plug those up as well
