Group K "Resto-Mod" Projects Page

Build-Up Recipes for the best  2-cycle PWCs 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 2cycle 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.
