Recently acquired a 1976 R90/6. It was one of those mythical bikes that was tucked away in the back of a shed covered with accumulated junk. Needless to say it pleads for some attention. I purchased a shop manual from Bob's BMW. Not much of a manual and short about half the pages. As a BMWMOA member since the mid 90's I'm aware of the countless articles on how to repair airheads, Keep'em Flying, Bench Wrenching and so on. Does BMWMOA have a searchable archive for these articles? Sure would help.
