WTB 1996 R100R evaporative emissions canister etc.

I'm looking to replace the evaporative emissions equipment removed by the P.O.

It's not just a question of being green. I sometimes smell gas fumes from the open vent on the bottom of the tank, especially after refueling.

Evap emissions equipment doesn't affect performance in the slightest, save an extra pound of weight.

Leads would be appreciated.

Also check your hoses from the petcocks, they might be leaky or loose.

Just a thought,

Unfortunately I lot of us took that stuff off year ago and threw it away. Check with some of the older BMW dealers.

This might not all be relevant. It's just what I turned up. The last link seems to include a link to more info on the IBMWR site. I found another lead from 2005 about changing cylinder heads, I don't think this is something that is normally done anymore. Plug the holes and go riding.

Not helpful.

The holes are plugged, and the bike runs fine. Petcocks are not leaking. I'd like to reduce emissions and mouthfuls of fumes after filling up. I've pulled the tank and it's obvious that fumes are coming out of the extra vent on the bottom of the tank on this evap.-equipped bike.

The links provided are all from people wanting to remove the smog equipment.

I'd like to hear from readers who may have this stuff sitting around their garage and want to part with it.

I actually have the external hoses that go between the heads and the air box, and inside the airbox valves that I took off my 1982 R100.

Send me a PM and we can get it sorted out.

I realized that only after I had made the post with links. Good Luck with it. I think there was one other doing replacement of emissions last summer maybe. Don't have that link.

I have all the airbox stuff if you need that, but that is the for air-injection... I think the OP is talking about getting the SHED equipment that vents the tank itself? Different ball o' wax....

would it be possible to run a hose from the vent on the bottom to the airfilter housing? sort of recycle the fumes. all that vent does is drain spilled gas. on mine, I have a hose from that vent to the bottom of the frame. anything that comes out goes right to the ground.

Do you have the drain hose for the tank vent in place?

Yeah, I was thinking about the air injection stuff too.

That's what I've got, too.

Originally, the hose would have been connected to a charcoal canister under the seat, possibly with a valve of some sort.

Right. I'm looking for all the stuff shown in this fiche, 11 through 15 with all the hoses, check valves, etc.

None of this stuff hurt performance, but it kept the gas fumes out of the air and my nose.

Just run a line from the vapor bung to a generic automotive carbon cannister.

In all my years with BMW's I have yet to actually see any of those parts you want. In fact, I have only seen a picture of the engine cover with the holes in it for that plumbing.

Another option is to search this forum for the few that have discusses the shed plumbing and may still have it, for example:

My California model GS has solenoids under the starter cover that shut off the fuel when ignition is off. Those solenoids might have a questionable electrical connection. If you do, bypass and go straight from tank to carb and report back! Now you will NEED to remember to shut off your gas when parked.
and another:

Man is this ever a silly discussion!

There are two attachment points under the tank for hoses. One is for the gas cap gutter, the other is a vent from inside the tank.

All of the BMWs before 1980? had none of the extra valves and garbage we've all removed. And you know what? I don't ever smell gas fumes! It's my opinion you're smelling fumes because enough gas went down the gutter drain to spill on top of the starter cover and evaporate.

First off, run a line from those attachment points back behind the transmission. Secondly, watch what you're doing and don't splash gas into the overflow gutter!

Really, it's that easy! Don't make such a big production out of it!

If you're smelling fumes without gas having run down the gutter drain, then there's something wrong. Either there's a split in the tank (rare, but I've heard of it happening) or one of the fuel lines is seeping - usually at the carb attachment point.
