The chain slack must be maintained to proper specifications. In particular, it must not be too tight or this will result in premature wear and performance loss.
The chain is an O-Ring type 530, with 116 links, model 50ZVM by Daido.
The slack specification is 40-50 mm (1.57 - 1.97 in.).
The spec for any ten link section is 150.1 mm (5.91 in.). The limit is 152.5 mm (6.00 in.).

The chain slack is the distance between where it rests (pretty close to how far down you can push it) and how far up you can push it. In this picture the rest position is shown with the yellow hand at the bottom pointing to the top of the chain as it rests. The yellow hand at the top should be the position of the top of the chain with it as far up as you can push up on it. This should be 40-50 mm (1.57 to 1.97 inches). I have mine set so that it barely contacts the bottom of the swingarm as it is pushed up.
To Adjust the Drive Chain Slack:
Loosen Rear Axle

Addendum:
After installing the 47-tooth rear sprocket the wheelbase decreased and the distance from the slider block to the end of the swingarm
increased as shown. This is with the 15-tooth front sprocket installed also.
