Adjustable cam wheels

The reason for mounting an adjustable cam wheel is to make a possible sharp cam stand 100% as you would like. Normally you can only adjust between one tooth to another. But an adjustable beat wheel allows you to adjust down to 1 degree of crank loss or less. You can also adjust the suction cam and the exhaust cam so that they open a little sooner or later, so you can get more power/torque at the top or bottom of the revs. It is optimal to try a little back and forth on a scroll bar so you can see the slightest effect change.
