Fits Yamaha R1 98-01 (4xv & 5jj), enables adjustment of ignition timing advance or retard by up to 10 degrees
Ideal for normally aspirated motors, advance the ignition a few degrees to gain a few more bhp or retard the ignition on turbo or nitrous oxide injected motors
Used but its as new condition
They cost around £60 new, I'm looking for £30 delivered
