Another indicator used by people is the three quarters rule
  6. Lastly, a basic feel of the tension of the chain between the cam gears can be performed if the engine is of twin cam design. Here, with the old chain installed there is roughly 6-8mm of slack when I pull up on the chain. Pushing down I get around the same 6-8mm of slack.
