STAGE 1 DETAILS
Perfect for motorcycles with a stock engine using the stock airbox, air filter, and pipes. Stage 1 Jet Kits are engineered to improve throttle response and deliver approximately 5% more horsepower than stock. These kits are fully adjustable to allow the use of well-designed aftermarket pipes and stock replacement air filters, like K&N.
STAGE 3 DETAILS
Get the most out of your modifications with a Stage 3 Jet Kit, which can increase power by 10 to 15%. Stage 3 Jet Kits are designed for motorcycles with a stock or mildly tuned engine using individual air filters instead of an airbox.
