[Description]
Open the right point cover, remove the disc with two points, and remove the two springs from the governor (spark advancer) at the back of the disc.
Made in Japan.
The feature of this product is that by replacing the old governor spring which is worn out, the advance position of ignition timing will be advanced to the position where the engine is completely blown out (1cm to the right side of F mark) without fail.The engine will be able to blow completely and you will be able to feel the power up.
In addition, when the timing light hits the alignment mark of the points, the F mark shakes irregularly to the right and left, it will be completely fixed by replacing the spring and the idling will be stable.
