I had a spare cr master on the shelf that I knew I coudl go to whenever I decided. However, the auction sight had a 2008 crf being parted out so I jumped on the new master cylinder. Honda added some sort of linkage to their front m/c in 2007. Sadly, it might be awhile before I can test it unless we are concerned with braking on snow and ice. So far, it feels incredibly strong and mush free. The part bolted right on and the stock brake line works really well despite the line attaching on the other side of the m/c.
