For the best possible cam timing this vernier adjustable cam gear is highly recommended, especially for competition use. Fits all models using duplex timing chain. The Vernier duplex, ie: twin chain, camshaft gear has a boss, which fixes rigidly to the camshaft, onto which is clamped the outer gear ring. Upon loosening the clamps, the gear may be rotated thereby adjusting the camshaft relative to the gear. Advancing the camshaft timing, that is making the full inlet valve lift occur before the rotation angle specified by the manufacturer, will make the engine produce more torque lower down in the rev range while losing a little of the top end power. Thus a vernier cam gear allows a camshaft's characteristics to be changed to make, say, a competition cam more flexible for road use.
