Resto-Mod Projects

Build-Up Recipes for the best 2-Cycle PWC’s to restore, and the most reliable mod packages for them.

There is a rapidly growing number of PWC owners opting to restore the lightweight & easy to maintain 2-cycle PWCs that they have enjoyed for many years. At Group K, we have been building the most reliable 2-cycle engine packages available. Our endurance racing machinery won more championships and titles than all other shops combined. We use the experience gained from these many championships to produce high-performance build-ups that offer the very best in reliability, fuel range, and performance.

This page has links to pages that give current build-up information on many models. These build-ups, called “Resto-Mods“, are centered around the models that we consider to be the very best and most restorable models for various riding applications. The focus of these build-ups is not to build race machines… but rather focus on the best in reliability, low cost, and fun-factor. New additions will appear on this page as we complete the “Resto-Mod” build-up documents.
