No sloppy shifting what so ever. I just remember what my old bike was like as I had their shift star in and to be honest I miss it. The crisp clean short shift is the way the bike should be stock I think. I just figured someone on here would've done it by now which is the reason I asked.Link said:I put one on a 636 & it was a huge improvement but my K6 750 shifts great. Are you having sloppy shifting problems?? You should just call FP & they will tell you exactly what you need to do.
