Not long ago a riding friend purchased a 1997 Yamaha SX 700 and wanted to install a different track. Back in the days of the trailing arm Yamaha models, we were swapping tracks with great frequency and had written an internal procedure for swapping the track on these models. This procedure was written for our own use, and was based on the 1997 and up trailing arm models, pre-SX Viper, but it should be fairly accurate for the Viper models as well.
We shared this procedure with our friend, and he asked us if something as valuable and time saving as this had ever been published in the magazine. We hadn’t, so here it is. It is by no means a replacement for technical competence or an actual service manual, but if you are qualified to install a different track in one of these models it will likely make the procedure much easier. Nobody from Yamaha service has ever edited or validated this, it is simply our “cheat sheet” from years back that should make somebody very happy. Ride on.
