I've just done the R1 shift mod to my gen1 and the difference is noticeable. The lever is slightly firmer to operate and the gears now snick into place more positively so that's all well and good. What is lost however, is the sense of fluidity to the change, it's now 'snick snick snick' whereas before I wasn't consciously aware of any mechanical action. Admittedly I've only just fitted it and ridden some 20 odd miles to evaluate it but that's my first impression. Everything is adjusted up correctly and all works hunky dory so I just wondered are there any different lengths of R1 shift arms to play with?
For me the perfect gearchange compromise possibly lies somewhere in between the length of the original shift arm and the R1 item that I have just fitted.
