Taller 1st gear? You mean front sprocket? Or you actually tore the gear box apart and installed a new gear? If so please pass the knowledge of this part on? Also did you run similar setups between the other gears? I have done this on quite a few race bikes but in all my internet travels I have not seen anything for the F800 so far. It is not really that it has fixed snatchiness it is the derivation of the power being transferred over a broader spectrum. I can not believe that this is a cheaper option because of the work involved in just pulling the entire motor and dealing with seals, fluid, and the necessary knowledge just to do this. A fuel mapping ECU and a sprocket change would be easier, cheaper and more pliable to adapt to different configurations... More information please.
