    I don't know anything about G/S's but to fit a post 81 gearbox you need to fit a post 81 flywheel/clutch....an starter has to be changed too as one less/more teeth. I have an 85 gearbox in my racer mated to a 73 motor...which has smaller 10 mm flywheel bolts...post 1975 (?) have 11.
    Fitting a later flywheel/clutch is a great improvement.:D
    They come up on Ebay regularly.

    S reg....about 1977? How did you find 'free camping' in Norway....we found there were bugger all flat places free to camp on. And had cars pull up and night twice and throw stuff at us.....probably thought we were German.
    Sweden it never got dark and we had to stay in the tent or get eaten by mossies.....:huh

    The RS is a '78. Build date Dec 77 according to the VIN No.

    Freecamped a few times there (on stream beds & ridgelines in Norway, or in Forestry blocks once we were closer to the Swedish border - not a lot in between), in Northern Germany (in Forestry blocks - site weren't the best), and also in France in the Alps. The Alps were the best, followed by the one pictured.

    One site in Sweden we must have just about been on top of a fox den, because we had pups playing around the tent after we went to bed. Another site we had a tussle with (what we think was) a Badger thru the tent fly, who was determined to take our food bag. The bag was fairly shredded when we got up in the morning.

    At that Swedish site, we had shooters come nr the camp (though we never saw them) - that made us very nervous

    My Fleabay purchase, from the UK. It'll cost as much again to get it here. 10+ kgs & bulky. Still way cheaper than new. Stainless 2 into 2. Tried to get dyno info & weights from Keihans - nothing available. They actually referred me to a German agent because the system has gone thru the TuV system.

    I've not resolved the gearbox issue yet - but I can fit the RS box & heavy (lightened) flywheel if I change the seal to a Paralever.

    Oh, and please please please can someone buy me these? I promise I'll be very good.

    i think I've got a set of those stashed away somewhere. I was gonna take them to the recycling...
    Seriously tho if they were that good they would still be manufactured & be featured on more bikes. 4 valves is 2 valves too many.

    Still pushrods. Not a 2nd cam.

    Jump from 68bhp to 82bhp. Totally worth it...buuut they did come with issues. The valve springs were too strong, so cams & followers became a consumable (every 30k miles or so). Higher compression, better breathing, better ignition (central spark plug rather than having waaaay off to the side). Huge money to buy new, back in the day, so not so many around.

    The oilheads are 4 valves. BMW just didn't go there with the airheads, which they had already had one go at killing off.

    BTW, I have a copy of that 2006 Classic Bike mag the ebay blurb talks about, if anyone wants a photocopy. Interesting stuff

    Back in 1990 I bought an R100RS from the BMW dealer in Clapham London.....it was a dog cosmetically but ran well.
    I rode it to work for a couple of years then decided to rebuild it. By chance I came upon two sets of Krauser heads, one set was pretty good and the other tired and there were no pistons. Bought them off a BMW tuner near Oxford for ...about 300 quid. I thought I had struck gold.....this was pre internet so info was not that easy to get...
    My local BMW dealer were not that interested in the older stuff but Bob Porecha in Sydenham was. They talked me out of the Krauser heads and I went twin plugged, 40mm Dells, later flywheel....the bike was amazing to ride....swapped the front end to a Brembo type one and fitted frame bracing. I sold the heads off to someone who thought he had struck gold.....
    I have heard of a set up here but they are not for sale as far as I know ..they are ex a Welly racer from the 90's ( I have been told).......My BMW guru says not to even bother with twin plugs on the racer. The high HP bikes in racing are using R80 heads with bigger valves and porting....but thats all I can find out on those so far.
    Thats my 2 fennigs worth on Krauser heads.....they do look cool though.:D

    Have to take it to work - the scanner here has 'issues' after Katherine tried to 'fix' a printer problem. :huh. PM your email address, & I'll flick it across in the next day or so.

    Got all my parts there. But my RS came from Park Lane BMW
    (actually a little garage a few streets back, way down in the bowels of the bulding - I think they were ashamed of it, so tried to get rid of it thru MCN).

    Those pistons are just weird looking, the valve cutouts are out 90 degrees from any other piston I seen. Was talking to a guy the other day who had his brother in auckland do a lot of work on his r80 heads and got huge hp gains with the head mods and mikuni carbs.he did a lot of welding and re-shaping of the ports and modified them to fit a huuuuge intake valve.

    BTW any Nads got an electric dremmel/porting tool? need to open up the inlet port and manifold on my Benelli.

    I've got a ryobi dremel if that's what you want. I don't think I'll be passing Richmond this week tho.
    Nutso some of your pics are coming across just as boxes with x s in them. Am I the only one with this?
    I was looking at a caferaceer last nite with these heads.
