The Semi-Direct Injection technology was unveiled by Ski-Doo in their 2003 model line. The system injects fuel into the transfer ports instead of introducing it into the crank case through the carbs, the way a standard sled engine works. It keeps fuel in the cylinder, not out the exhaust! Our Big Volume Pipes and Cans will work with the SDI engines because our fuel flow rates are similar to the map Ski-Doo put into the SDI system. As we start working on the ports and raising compression, the fuel flow rate goes up, resulting in the need for a richer fuel ratio. We have solved this dilemma by utilizing a proven, adjustable fuel management system. Simply put, the Fuel manager allows you to add extra fuel these modified engines require without losing the low emissions benefit of SDI.

We've learned a few things about clutching and clutch kits over the years that we'd like to pass along to you:

1. Nothing replaces good old-fashioned testing and taking notes.
2. We aim our clutch kits at aggressive trail riding, delivering strong acceleration for straight-line running and solid back-shift for corner to corner action.
3. Second-rate components deliver second rate performance. We use Dalton Industries components in our clutch kits and Dalton in our race sleds and they have distinguished themselves as high quality parts. We thought you'd appreciate having the same quality in your own sled.
4. Every clutch kit doesn't have to have a helix, springs and weights or ramps. If a stock piece proves the best in combination, we don't think you should have to buy the identical piece as part of a kit. That's what sets us apart from some of our competitors and that's why there is some variation in our clutch kit pricing.
