I don't think the BMW method is any better, just a little different. It's what they've published since maybe the mid 1980's. Pretty much a matter of what Jock and Scout said .......... don't forget to measure at the tranny. BMW sets handlebar lever gap from the back of the transmission. I guess I never gave it any thought, since the clutch has always, until recently, taken up gradually, offering some feel so one could use the clutch lever as a control instrument, not an off/on switch.
The last time I had tranny work done, there was no gradual take up of the clutch. Oh, it disengaged and engaged, but all near the end of clutch handle movement. Also, took considerable care to match engine rpm closely with road speed to avoid grinding the shift dogs. I thought, 'well, something isn't right in the clutch or tranny.' Maybe a new clutch plate that is out of spec that'll wear in. So I soldiered on. Until yesterday. 15 minutes of adjusting, and I had my old bike back. Long time since I've had her out for 120 miles.
