Key TSP Head features are:

  • Drastically improved throttle response in the whole RPM range
  • Smoother throttle response
  • Much better part throttle power
  • Much more enjoyable to ride

TSP head options are as follows:

  • MEDIUM COMP – this head suits the majority of trail riders and hard enduro racers who want better bottom and mid power and a small gain up top as well. The power delivery is much stronger and more tractable than stock but still super smooth and suits a wide range of riding conditions. Works with 91 octane fuel.
  • HIGH COMP – this head suits riders who want harder hitting power everywhere, especially down low. It completely transforms the TBI into a trail weapon. This head may push the limits of normal 91 octane pump fuel at sea level under certain extreme conditions, but it can be used in normal trail riding conditions safely in order to achieve maximum bottom/mid performance. This head can be used at elevations above 3,500′ to approximately replicate a medium compression head at sea level.

TSP Head/Insert work best when used together with an ECU reflash completing the package, and it is highly recommended doing an ECU tune at the same time as the head to get the best results. The TSP  Power Kits provide the best overall solution for your TBI.

All TSP mods are designed and dyno tested in-house at TSP so you can be sure you’re getting reliable performance and a quality product.
