That's why I would like to see someone else do it. I am a visual learner...The service manual documents it pretty well. Remove right crankcase cover page 12-57 / 5 min. Remove dual clutch page 12-66 / 5 min. Remove reduction gear cover page 12-70 / 5 min. Remove gear shift linkage page 12-73 /5 min. See picture bottom page 12-73 arrow #3 shift drum center bolt. Whoot there it is. Times are approximate. I could be wrong. I am not a motorcycle mechanic. It always looks easier than it is.
