When I looked into doing this on a car shaft some years ago, I drew a blank because the joints with replaceable needle roller bearings were larger and boring out the 'eyes' would have made the shaft a lot weaker.
Sorry Vox no markings on the U-joints and I sure looked.But that's not unusual, most of the automotive ones I have seen don't have any markings either.That makes differentiating the good from the bad harder, lots of cheap Chinee out there and even them are getting good at faking the packaging.
Pretty crafty that Bruno, he finds enough room to cut grooves in the yoke and install a circlip and that without adding any more metal to the yokes.
And that reminds me that I should have measured the lenght/cap width of the new U-joints and compare to OEMs, maybe his are a little shorter and that is why he can get away with circlips and no extra metal on the yokes. Will do next winter and take pics of that repair, last time I just wanted to install and ride.
Looks like some of the GS guys are getting theirs done in the USA also and as far as I know BMW has the same U-joints all across the models/years going way back to the introduction of the Paralevers in 1988.
That's just when they started having driveshafts problems, the introduction of the Paralevers and they do fail early, my 90 GS only had 20,000 Kms or so when the front disintegrated and smashed into the swingarm leaving me stranded in the boonies.
