Hey all,
Doing a top-end re-seal on my '78 R100RS and decided to address my sticky enrichener mechanism and 40 year old "cables".
On disassembly, it appears whomever was in here last used aluminum anti-sieze as a lubricant, which had turned to a thick, sticky, hardening muck.
Now that it's all mucked out, I'm ready to reassemble with the new cables. I've searched this forum, Google, Snowbum's site (and I now have ten other rabbit holes open in tabs -Thanks Bob!), found no mention in Haynes or in my Bing manual.
I have ideas, but I would like to ask for input on lubing this system.

Thanks

Ok I ended up using some EP moly on the mechanism and WD40 for the "cables"
If anyone is curious, I'll post long-term results..

1978 models have the enrichener control lever on the LH air box case and short, un-lined cables. On those I use a "cable luber" to pump chain lube into the cables before complete assembly. Chain lube is generally waterproof and very tenacious, making the job a lifetime lube. I don't put anything on the cable-to-carb mechanism.

I'm with you on using a cable luber, but I would NEVER use chain lube on a cable. Most of them nowadays have thickeners so they stick to the chain, but in a cable sheath, especially at low temperatures, they'll make it difficult for the enrichener return spring to move the enrichener crank back to the "off" position. There are several cable specific lubes on the market, and I've had good luck with Triflow and Boeing's T-9. All of them are thin enough to easily run through the sheath during application and they'll stay thin at low temps. WD40 is NOT a lubricant at all, but a solvent and a moisture displacer. Prolly good for cleaning out old gunk (or chain lube) from a cable, but not very good for makin' 'em slide nice.

$.02...

Thanks ya guys.
I couldn't help it: I pictured what a squirt of PJ1 Black Label would do in those housings...Even so, couldn't be any worse than the aluminum anti seize that had worked its way in the old ones.
I've heard (read) some say don't use anything at all on the wire "cables", but i figured at least some "Water Displacer 40" would be a decent bet.
Tri-Flo's a good thought. Maybe I'll do that.

The enrichener cables I'm thinking of have a rather stiff solid center wire that pushes the valve closed, it's not a spring return type cable. Thick lubes are OK on those cables.

The later model bikes use the more traditional braided center wire, and those do have a spring return. You're correct Scot, I would not use chain lube on a spring-return cable.
