This Thunderstroke® Stage 2 Performance Kit delivers 17% more horsepower than a stock 116 ci engine along with significantly improved throttle response and proven reliability and ride quality. Dealer installation is required, as your dealer will replace several internal engine components, including the cams, with high-performance Stage 2 equipment. The dealer will also upload revamped fuel mapping to tune the Stage 2 116 ci engine for optimal performance. The Thunderstroke® Stage 1 Performance Air Intake and your choice of the Stage 1 Oval Slip-On Muffler Kit or Thunderstroke® Stage 1 Slip-On Exhaust Kit are required (all sold separately).
