Title: 85 or "European" cams
Post by: Dewey on November 19, 2012, 09:08:12 AM

Are the 1985 cams or the "European" cams truly different than other K100 cams? If so, can anyone furnish actual numbers such as lift, duration, timing? Are they a different part number?

Well, I think that I have found the definitive answer to this question and that is this:

According to specs from a German, UK and US factory service manual and cross-checked with the Haynes manual and BMW part numbers, ALL K100 2V cams are the same EXCEPT for California bikes. It seems that the difference is that worldwide and 49-state bikes got cams with 284 degrees duration and CA bikes got cams with 256 degrees duration. BMW lists the standard cams and CA cams.
