Just cut my finned exhaust nuts off, to find that I don't have the 'normal' (according to my Haynes Manual) compression ring and clamp ring arrangement, but just a single ring - see photo.
The thread on the cylinder looks pretty good (though I haven't cleaned all the old crap out yet), but when I offered up my shiny new finned nuts (motobins) its not an obvious match.
It might just be that a need to clean the thread, but is there a chance the I have a different thread on my new finned nuts?

I would check part numbers for the finned nut across the model range, it may be that they changed, although I would be surprised if they did.  Of course, the exhaust nut is different from other air heads, so you may have the wrong one.

Of course, when you install the new nut, use some anti-seize so the next mechanic in doesn't have to cut this one off.

I don't know the specifics but remember a couple of things from reading.  As usual, the R65 is a little different than the others.
The finned nuts on the R65's are smaller than the other models (I can't remember if the small version was used on other models or not).
I'm pretty sure that there is only one other piece involved, the gasket that goes up against the head.  I've heard of other models that have a multi-piece thing but the R65's just have one.

The single clamp ring is correct for the R65, except for the very early 78/79 models which had the same arrangement as the bigger bikes. BUT, if the nut has been changed on the earlier bikes, the baulk ring will have been discarded as the later nut bears directly on the clamp ring.

Thanks for the replies - I've checked and it must be the correct nut, so I'll just get on with cleaning - Do you know what pitch the thread is?
Also trying to replace the crossover pipe which is not wanting to come off - any tricks to get this apart?

Alternate heat and freeze spray, along with lots of 50/50 ATF and Acetone. Once you start getting a little movement you are getting there.

For putting back together, I'll be getting some copper anti-seal for the finned nuts. Is there anything recommended for the cross over pipe?

+1 for a thread file. I cleaned up a very worn stub enough with a thread file to hold a finned nut to a decent torque. It was much more worn than yours from what I can tell from your photo.

I'm going to need to get the bike imported from england (originally registered in 1980) to france where I now live - Any pointers on how best to achieve this would be appreciated.
I understand that the first thing I need to do is get a certificate of conformity and this is best done in england rather than in france - does that sound about right?

Further to my last post
Am I right in understanding, that the reflector and the glass (lens) will need to be changed for RHD?

I've started a searching on German ebay, which should be a good  starting place.
If they do insist on getting km on the speedo, does anyone know if the gearing will be the same for the km and miles versions for the R65, and whether there is a way to somehow just change the plate with the speed markings on it? (There is a "for spares" km speedo on german ebay for 30.....and a working one for 169, but even though the references are both W793, the position of the markings appears to be different, so this might be difficult...?)

After a bit more research on the ratio (W value) on the speedo with mine being W = 1276, the km equivalent is W= 793, so in theory any continental speedo with this value should give the correct speed.....
I've found someone selling what I need in France, he has asked me to make him an offer - any suggestions on a good price to offer appreciated - I suspect he is taking his machine apart to turn into a cafe racer....

torque settings for 1979 R65.

Does anyone know of an online resource for torque settings?
I have the haynes manual, but there's only limited info.
Specifically looking for Front Disk brake values which I'm re-installing after having taken apart)
Also about to clean up my flat top carbs, so any info on that would be useful - thanks

If you mean the bolts that fasten the caliper halves together there isn't a published torque value on the basis that you are not supposed to split them. When I did mine I used a low figure, somethinh like 15-20ftlbs.

To my knowledge there are no torque value for flat top bings either. As there is nothing that needs to be particularly tight I just go by feel and tighten everything lightly. In particular don't overtigniten the main jet holders or the top cover screws.

Thanks to everybodys help to date, yesterday I enjoyed my first (very small) ride on my 1979 R65!
Heres what I now need to do:
After rebuilding the calipers and replacing the master cylinder, I filled the system to find one of the seals is gone on the right hand Brembo Caliper - unfortunately I have the 36mm piston so I set of seals will set me back 42,60 (before post....!)
Next issue is adjusting the carbs - is this possible without the proper kit?
Any information / guidance on this would be greatly appreciated.
