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.
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.

Feel all around the bottom edge of the gas tank and see if its moist. I had a weep coming from one of the welds at the rear mounting bracket under the tank. I think Wirespokes has it correct.

R100 heads

Pair of heads that came off of a 1978 R100s. Large valve with air injection. Not original heads. Unknown miles, good condition except one needs the exhaust threads repaired and some nicks in a fin or 2.
150.00 or make a nice offer. Pics: http://razzi.me/a/22552

The heads in your pictures are not '78 S heads. They're at least '81 or newer.

Completely different animal for anyone who's specifically looking for '77 or '78 S heads.

fwiw.

R80ST parts

I have a couple of take-offs from an '83 R80ST in very ordinary condition:
  • chrome handlebars (same bars as on the Slash 6 (60/6, 75/6, 90/6) GONE RIDIN'
  • headlight bucket (bucket only, no lens, lights, wires, etc) (same as R65)

I recognize that neither of these has any real inherent or intrinsic (huh?) value... if anybody wants or needs them, let me know and I can sell real cheap plus postage....
