Stage 1 at 8350 RPM works on a stock ski for about 74 mph. At 8500 RPM you need a ribbon delete for about 75 mph, and at 8600 RPM aggressive timing calls for a ribbon delete plus Torx cooling kit, also near 75 mph.
Stage 2 (8600 RPM) requires a ribbon delete, Torx cold air intake, Torx Yamaha catch can and basic cooling kit. Please call if you have questions about which stage fits your ski.
