http://www.factorypro.com/prod_pages/prodk35_ex300.html
Not sure if you guys have heard of this product but I went ahead and ordered it since being on the track and experiencing some of this. I can account some of the miss shifts to driver mod use but there where a number of times during the course of the day where the bike actually downshifted out of the blue. Again I think some was rider mod issues (lazy shifts) but..... if this can help I am game. So if your in the same boat I will let you know how it works.
Improve lazy shifting - virtually eliminate missed shifts - virtually eliminate false neutrals - help prevent gearbox damage caused by missed shifts. I did get the ceramic bearing options as well.
