Dynojet has been leading the motorcycle and ATV industry for years with their ability to produce the maximum horsepower out of engine by adjusting the fuel/mixture and their jet kit exemplifies quality and performance.
Stage 3 Jet Kits are intended for motorcycles with stock or mildly tuned engines using a well designed aftermarket pipe and individual air filters. In most cases power increases of 10-15% can be achieved. However driveability may be compromised particularly with short stroke, high rpm motors. On some modern engine and airbox designs, individual filters and proper jetting offer no performance improvement yet compromise driveability, in such cases stage 3 kits are not available
