    Default Sx chassis e start mod.

    As many know the electric start vipers xtc vmax ventures and sxr have the ring gear mounted to the primary clutch. Over time it comes loose and wears the clutch pilot where it mounts. I modded this clutch to use roll pins so that it drives on the roll pins before it drives on the bolts. Clutch balance was checked after install. Now to get it installed and see if it works.

    well we had failure this weekend on this sled. i do not know if it was the mod that failed 1st or the primary spring causing the belt to slip making heat to cause the locktight to soften so that the bolts loosened up. have to take it apart this week and replace the less than 1000 miles primary spring that failed with an old one for the riding we have left.

    Green loctite (sleeve retainer) is the way to go. Held great for years now and I put them through dishwasher once a year and no problem.
