Easy for many karts, others might take a bit of finessing, depending on the attachment of the shift lever, and the steering supports that are part of the frame. To get it to work on a TonyKart, we had to have a sleeve machined that had non-parallel axis paths for the inner (lever arm) and outer (Honda clutch perch) diameters. It also had to be doweled to the shift lever, as it wanted to slide and rotate a bit. Has been working great for many years. Another note: The Honda cable in the video is actually for a CR250. The engine end is identical to the 125, but the perch end is slightly different, requiring a bit of machining to the perch. The 125 cable would work great, but I was stuck with the mis-matched parts and had to make the best of it, with no time to re-order. The 250 cable is slightly heavier, and it works so very smoothly. I first put this setup on in 2000 when I got the kart. Last year I finally replaced the cable, as the original had worn through a liner and the function had degraded. At that time, I also installed a ball-bearing kit in the lever pivot spot. I'd sure like to get another one, but that source from many years ago has disappeared.
