Slack chain efficiency training

chain tugs work nicely. I have a spare 8MM MKS one if you want it. Keeps chain nice and tight.

I personally hated that bit of give, drove me nuts. Trackstanding is easier without the give as well. Your machine just runs so much smoother with a taught chain.

chain should never be "taught"

will create loads of resistance and wear things out quicker as whatfriends has mentioned.

Removing slack is good for a solid 'direct' feeling favoured by those who like to do backwards circles and the like.

But A bit of slack in your chain will make everything last longer, and spin smoother.
