I'm going back to this old post because
I'm starting to have the problem
On my motorcycle.
Can you tell me where this setting is that you mentioned.
Thank you.

In this video after two minutes the adjustment is made.

Look at right side of engine below crankshaft there is a balancer shaft.
Loosen 10mm m6 bolt that clamps the balancer shaft.
Mark the position of the shaft with a marker pen.
start engine and slowly rotate counter clockwise, listen for the "whine" ( bad noise ) STOP and rotate clockwise 20 degrees.
tighten up the 10mm m6 bolt that clamps the balancer shaft.
Finished.

Most people never adjust this and a lot of bikes make a little noise, it also makes a difference what oil is used, a few riders notice that after the first oil change this noise starts.
Here is what's inside, the balancer shaft is excentric and you are adjusting the space between the gearwheel teeth by rotating the shaft closer to the main gearwheel on the crankshaft;



The balancer shaft rotates in the opposite direction to the main shaft and reduces vibration, this identical system is employed on the cb1300 which has a similar engine.

Whilst riding yesterday i had a thought about this noise that sometimes appears when the oil was changed by several members;

The eccentric shaft is also hollow and has oil pressure eminating in the middle of the balancer, it rides on an oil film similar to the crank shaft, so if the viscosity changes the balancer can have a different amount of play between the gear teeth and the shaft.

And like all other moving mechanical parts it would wear in and and thus have some additional play after some miles.

Just adjusted mine yesterday and i did notice that the "tick tick" noise around 1500 rpm has almost disappeared, it started creeping in at 39.000 km and although it did not worry me it's still better not to have to listen to it.

When making the adjustment try to get it so the noise is barely there, too tight and it may wear out too soon and start loosing oil pressure.......
