In this video, I am replacing the Throttle return spring on my Yamaha R3 with a Norton Racing Soft Pull Throttle Return Spring. This Spring is softer than the OEM spring and provides a much lighter, easier pull on the throttle when a race throttle system is installed. As a result you will need less force to twist your throttle resulting in a more “gentle” throttle and offering better throttle feel and control. This small change will make a big difference when spending long hours/days on the track.
This is a fairly easy modification and shouldn’t take much time to complete. You will be able to feel a BIG difference very quickly with this modification.
