Obtaining maximum power from an engine is what everyone strives for. When it comes down to tuning at the track, carburetor jetting is one of the key essentials to a successful run. A mixture that's too rich will have a severe effect on performance, and a lean condition could severely affect the long-term reliability of pistons, valves and other internal engine components. The MaxJet™ Precision Fuel Tuning System provides the racer with a finite linear fuel curve that always makes a difference in performance.
