Drive shaft

Post by Trapperjon »

Hello all,
I was lucky enough to inherit a R100rs (1979) this year, though it had been standing since 1982 in a concrete garage in damp cold UK it was a complete bike, not so now as I'm restoring it and it's in boxes you could say the boxer is boxed.
I'm new to BMW I've always been a Kawasaki man but I'm loving a different project to what I've had before.
Does anybody out there know if the drive shaft UJ can be replaced or do I have to purchase a new shaft?
Regards
Jon

They can be replaced, by those who know how.

Moderators, can someone help this guy out and move his thread to the proper forum?

Why would the u joint need replacing if the bike sat so long?
How many k's?
The bmw airhead u joint was not intended to be seviced, so it isn't a straight swap.
There is a small amount of welding required with the fix.
A mill would be nice to have access to for removing the original retaining stakes.
