Features
  • This modification utilizes the Factory SuperJet 'Mod' Pipe to replace the restrictive OEM exhaust canister. The Mod Pipe features a tuned exhaust chamber and manifold that dramatically improves horsepower throughout the powerband.
  • RIVA Flame Arrestors, Filters, Filter Covers and Adapters are installed to increase airflow to carbs. No internal carburetor modifications are performed. High and low speed screws are adjusted to optimize carb settings.
  • RIVA / Boyesen Reed Stuffers are installed into stock cages with stock reed petals. Stuffers increase fuel / air velocity through the intake tract, resulting in increased throttle response and acceleration.
  • ADA Billet Girdled Cylinder Head is installed with 35cc domes producing 175-180psi compression. Increased compression produces more torque and acceleration. Girdled design prevents cylinder body from cracking.
  • MSD 701 Enhancer Ignition is installed into OEM electrical box. Enhancer improves power with a hotter spark and features an adjustable rev limiter.
  • Tri-Loader Intake Grate is installed significantly enhancing handling characteristics. Prop spin and cavitation found with stock intake grate is greatly reduced.
  • Solas YB-SC-J Impeller is installed. Superior hub design and variable pitch blade angle deliver improved performance with reduced cavitation. Billet Impeller Cone included.
  • R&D SuperJet Ride Plate is installed. Improved plaining surface, rear contour shape and a D-shaped bottom hole improves handling performance through reduced porpoising, increased high speed stability, improved traction and cornering.
