HPV Packages

Bolt it on, gas it up and go!  Your HPV motor package will come complete with motor, carburetor, filter cup, clutch, clutch guard, pipe, header, flex, coil, spark plug, instruction manual and decals.  All you need is your kart, motor mount, and air filter.  Its that simple!

The purpose of the spec motor package is to provide a user friendly place for the racer.  By eliminating the complicated and expensive process of clutch adjusting and pipe tuning, the HPV 100 has put racing back in the hands of the driver.  Experienced or not, the HPV provides the most competitive racing available in 2-cycle karting.

The HPV 100 is supplied with a single disc, dry design, EXPD clutch.  The EXPD is a direct drive clutch; once it locks up it does not disengage until the kart stops.

The exhaust system for the motor package is designed to approximate the horstpower of current sportsman classes.  However, the exhaust will be quieter and look like an attractive expansion chamber. 
The exhaust systems for juniors and seniors are slightly different in order to regulate horsepower.  They are both designed to provide a wide powerband.

The junior class packages have a smaller venturi Walbro carburetor which eliminates the tuning problems common with restrictors.  The senior class carburetor incorporates the popular WB3A Walbro.
