On any ATV you can gain power by making adjustments or changes to the fuel, intake and exhaust systems. One other way of making or changing the power delivery of your engine is through the adjustment of the ignition timing. Vortex has been making CDI units for both ATV and dirt bike applications for years, and now it has integrated its fuel interceptor for EFI systems with its fully programmable CDI unit in one package for the Suzuki LT-R450. This plug-and-play setup comes preprogrammed with 10 fuel and spark maps to adjust the engine's power and torque characteristics. Further fuel adjustment can be made via three rotary switches, changing the fuel delivery by as much as 12.5 percent. Kill two birds with one stone in your quest to get the best performance for your ATV while getting the most for your money.
