This series covers how to tune a Honda GX160 to raise performance. The same procedures apply to the Honda GX200 and popular copy engines. Part 1 is the full strip of a GX160 (GX200) Honda engine in preparation for tuning. Those methods also work on any Honda GX range engine or clone equivalents. Later parts cover performance upgrades for the GX160 / GX200 kart engine. On a typical budget the stock 5.5hp GX160 can be taken to over 20+hp by changing readily available components.
