YAMAHA FZ6 Fazer 600 5VX ALL YEARS 2004-2017 4º IGNITION ADVANCER ROTOR REPLACES F7T564 These advancers are designed to increase performance and improve throttle response particularly in the low to mid range as well as improving the starting of the bike. Bikes are designed to run as well as possible using the worst fuel available in the world and so have slightly retarded ignition to help with this. As we have relatively good fuel we can afford to run the bike with these 4º advancers fitted and have the bike run a whole lot better. These advancers are magnetic stainless steel to prevent rusting and for more durability. They are also very easy to fit so this is one of the best and simplest mods you can do, it is also an inexpensive way to get more out of the bike.As these are a bike modification we do not accept any responsibility for the fitting of our products. These are fitted to the bike entirely at owner's risk.
