Yes, they are interchangeable.

As for durability, I can't say anything about the Chinese covers but I've seen both the peanut and /7 covers wear through in a slide on pavement. If gthe Chinese covers are less durable then it's just a matter of sliding distance before they wear through relative to the others. Either way, you've got to turn them upside down.
Yup. I have a 95 GSPD Classic. Peanuts (though I never called them that before reading this thread)
I bought a couple sets of reproduction covers from Bob's BMW. They were just fine.

Totally right ! That's why I prefer /5 second hand valves cover than repros. Here, Europe, second hand and repros are at the same price.
Those at BMW dealer seems to be also chinese now
Old ones are heavier (more aloy) casting is better, walls are larger
Like many BMW parts quality is not at the rendez-vous like back old days... I think also about ruber boot on carb gas wire that are totally crap and last less than a couple month were the old ones on my Silver smoke had last maybe 20 years

I just came across this when swapping out my left side cover (patched by PO).
I picked up a repro cover and realized the studs were too short to get the nuts on... I was tired, so I put some loctite on them and only screwed them in partially. I should probably do it right and pick up the correct bolts.
Looks like they're pretty cheap:

Heck no, those fit all airhead twins from 1951 until 1996.
They do not fit the ill-fated exploding Krauzer heads.

What is really cool is that they were made in the USA!

Why are you trying to lead these guys astray again?

I bought those valve covers from a small importer in Cleveland's Industrial Flats ("There You Go Again Performance Bikes") back in 1982. They fit five-valve Rensport "Autobandenstormer" heads. Very rare, very special and very expensive.

Gotta know what you're lookin at kid!

I'm surprised how many people think those valve covers are indicative of Krauser heads.

Man-o-man... You cant be any more supervised than I am! I get that Krauser Heads question constantly but at this point it's become funny instead of mystifying or annoying. Nothing looks like Krausers, except Krausers!

Hey... And you know what? Wirespokes recently dropped by for a two or three day visit and he mentioned that he actually owns a set of Krauser heads that he isn't using!

Krauser heads.... Me want!

Yeah, there is one proudly on display, but it's the last one, forever.
They don't make them anymore.
Molds are done.
They do still have the o-ring gasket sets. Plenty.
I made sure of that before I left.

Icky! Just shows to go you how one man's elixir is another man's poison...er, or something like that. To me, those CC (Crazy Californians?) valve covers just took the original turn for the worse in valve cover design and turned it for even worse. Glad to hear that the molds are toast.

Sorry, but my brain's still wet from an afternoon ride to Windy Pass Mt. St. Helens last night.

Question

hi,

i have a valve related cover question for you.

both left and ride side of my center valve cover bolts rods are shredded (on the valve block side).

the bolts are double sided with reverse groves, the bolts now spin freely and pull any excess metal from the valve block, a proper seal is no longer there. i.e. oil leaks and generally undrivable. Does anyone have any experience with this who can help. short of buying new units, what is the best course of action, re-grove and use bigger bolt rods? then i would have issues with the original outer bolts. any ideas of engineering techniques would be welcomed.

1978 R80/7, newer type valve covers ;)

About a year and a half ago I saw the display cover at SJBMW and asked if they had a set. They in fact did. Chris indicated that they had gotten several sets from the powdercoater who discovered them in a box under a bench where they had been hidden for many years. I bought a set and waited while the sales guy ground off the powdercoating on the fins. The powdercoating was black gloss rather than the satin finish I think the earlier CC Products covers had. I've yet to install them. The original intent was to put them on the R100GS for their additional robustness but I decided not to since I've dropped the bike and tweaked the crashbars enough times to make removing even the stock covers a hassle. The current plan is to put them on my 83 R100RS Turbo if and when I ever get going on that project. One of my next chores is to repaint two sets of the stock black covers.
