HOUSTON'S PREMIERE HIGH PERFORMANCE TUNING
STAGE I TUNING
EXHAUST + INTAKE + TUNER
The easiest and most cost-effective step to improve your motorcycle’s performanceis to increase the airflow into and out of the engine. A high-flow air cleaner and system-matched slip-on mufflers provide horsepower and torque improvements you can feel throughout the RPM range, and serve as the core components for all performance upgrades.
STAGE II TUNING
STAGE I + CAM UPGRADE
Adding performance cams to a Stage I equipped bike is the next step to improved performance. Cam choices allow you to tailor the engine’s performance to your specific needs. A “torque” cam offers on-demand throttle response from low to mid RPM at cruising speed. A “power” cam targets high-RPM, wide-open throttle response that keeps pulling right up to redline. ECM calibration tuning is required to accommodate the increased valve timing, and performance valve springs may be required for high-lift cams.

STAGE III TUNING
STAGE II + CAMS + BIG BORE CYLINDERS & PISTONS
The next step on the performance journey is to build a “bigger” engine. An increase in engine displacement allows the engine to swallow more air and fuel, a higher-compression piston squeezes the air/fuel into a more volatile mixture, and when combined, generates more power when ignited. A displacement and compression increase provides torque increases throughout the entire RPM range with a 15-25%improvement in the mid-range power. ECM calibration tuning is required to adjust fuel flow and timing to accommodate the increased displacement.
STAGE IV TUNING
STAGE III + CAMS, BIG BORE CYLINDERS & PISTONS, CYLINDER HEADS & THROTTLE BODY
To maximize the impact of the increased displacement gained with Stage III updates, the addition of free-flowing ported cylinder heads and a big bore throttle body top off the performance build. Designed to satisfy the high-RPM, throttle-twisting rider, the Stage IV update delivers 20-30% increase in power that keeps pulling right up to the redline, without sacrificing mid-range torque. ECM calibration tuning is required to add more fuel, and a higher-lift cam may be required to deliver maximum power.
