We are dedicated to "Max-Performing" your bike. With 25 years of experience, our specialty is porting two and four stroke motors to their maximum potential. Port timing, intake, exhaust flow volume, and direction are taken into account when porting your jugs. We take the time to open up your intake, transfer, and exhaust flow paths for MAXIMUM flow. This makes a HJR dune or drag port much faster than ones done by our competitors. We can send individual parts or assemble the whole motor and ship it to you.
