Although this compression ratio is only marginally higher than stock, the improved dome design gives better throttle response and smoother, more linear power delivery everywhere, especially when combined with a TSP ECU tune. The power delivery is stronger and more tractable than stock and suits a wide range of riding conditions. Works well with 91 octane fuel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHIGH COMP\u003c\/strong\u003e – this head insert is higher compression than stock and provides significant increase in bottom end and mid range torque.  Suits expert\/pro level MX at sea level with higher octane fuel OR trail riders and intermediate racers at sea level with 91 octane pump fuel. This head insert is ideal for elevations above 3,500 feet, and may push the limits of 91 octane pump fuel at sea level under certain conditions, but can be used in normal trail riding conditions safely in order to achieve maximum bottom\/mid performance. Likewise, intermediate racers who are not revving hard all day can get away with this head insert at sea level on pump fuel. If you are using this head insert at sea level for faster MX, deep sand riding or in very cold weather we would suggest running the softer\/richer White map and\/or some higher octane fuel. This head insert can also be used at elevations above 3,500′ to approximately replicate a medium compression head at sea level. Above 3,500′ it is perfectly safe for 91 octane pump fuel under any conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eOur Heads\/Inserts work best when used together with an\u003cspan\u003e \u003c\/span\u003eECU reflash. It is highly recommended doing an ECU tune at the same time to get the best results.
