BMW has released collections of Service Information Bulletins for motorcycles built in the 80’s (plus or minus a few years) on two CD products.
I was able to purchase the fist CD (version 1.0) about a year ago. It was obvious incomplete, but had quite a bit of useful information – particularly for my ’87 K100RS. As the CD includes Service Information Bulletins from the 80’s, it also covers R series motorcycles. I recently discovered a second CD was produced, version 1.1. I ordered it from MaxBMW, but the order was cancelled and refunded – I’m not sure of the status of this product.
I’ve come across various BMW Service Information Bulletins posted here an there on the Internet – but haven’t found anything comprehensive. There may be copyright issues in sharing these – but I’m suspicious of BMW really wanting to restrict the access to this information. After all – it’s a gold mine for owners of old bikes wanting to maintain and restore them – and buy new parts. That – and all the bikes covered are clearly well off warranty – and unlikely to produce new warranty service claims.
This screen image below shows the two CD’s on the MaxBMW fiche for ’84-’89 K100RS motorcycles in the “01-Literature” section titled:
01_0985 – REPAIR/SERVICE/MAINTEN. NON-CAR-SPECIF.
