This video demonstrates a quick shift sensor installed on a 2007 Yamaha R1 (YZF-R1000) motorcycle. The quick shift sensor is a device that allows the rider to shift gears without using the clutch. This is done by sensing the shift lever position and sending a signal to the ECU, which then cuts the ignition and fuel injection for a brief moment. This allows the transmission to shift gears smoothly and quickly. The video shows the rider shifting gears up and down through the gears. The quick shift sensor works very well, and the shifts are smooth and quick. The rider is also able to perform clutchless downshifts, which is a very useful feature. The video is a good demonstration of how a quick shift sensor works. It is also a good example of how a quick shift sensor can improve the performance of a motorcycle. Additional details: The quick shift sensor is a Danos Performance quick shift sensor. The ECU is a Superbike Unlimited reflashed ECU. The quick shift sensor is installed on the shift rod. The quick shift sensor is wired into the ECU. The ECU is re-flashed to allow the use of the quick shift sensor. Technical description: The quick shift sensor is a device that senses the position of the shift lever. When the rider shifts gears, the quick shift sensor sends a signal to the ECU. The ECU then cuts the ignition and fuel injection for a brief moment. This allows the transmission to shift gears smoothly and quickly. The quick shift sensor can also be used for clutchless downshifts. This is done by sensing the position of the shift lever and sending a signal to the ECU. The ECU then cuts the ignition and fuel injection for a brief moment, and then applies the clutch for a brief moment. This allows the transmission to shift gears smoothly and quickly. #YamahaR1 #MotorcycleModification #DIYMotorcycle #MotorcycleTech #MotorcycleTutorial #MotorcycleRepair #Quickshifter #MotorcycleUpgrade #SportBike #Superbike #DIY #MotorcycleDIY #MotorcycleMaintenance #MotorcycleTuning #MotorcyclePerformance #MotorcycleEnthusiast #MotorcycleRider #MotorcycleCommunity
