Found this list on another site and just wanted to get some of the members of this forums feedback.
I would not regard any of them as "essential" for working on an airhead.
My reasons are that quite simply there are BMW specific publications available both on the web and commercially that are significantly cheaper than anything with a Clymer badge on them and are significantly more relevant. For example, whilst any electrical manual is of assistance, the
one published by [ forgot name but something like Euromotoreletrics] is infinitely more relevant as it not only covers basic principle, but then delves into the peculiarities of different model airheads.
Similarly service and repair manuals dealing specifically with airheads are of greater assistance than generalist publications.
In short of I would keep my money in my pocket and if I was to buy anything I would buy publications specific to the airhead.
