I noticed on the In Motion site that they sell a primary chain tensioner.
Would this be something I should get?
I figure if the chain is ok, it would be needed, but if there's some sort of advantage in it, I'll go for it.

Even with a new chain there is a bit of slack but it doesn't ever seem to cause any issues. I've never noticed any back lash problems with my MAR and there is nothing inside for a slack chain to rub against either.

Many thanks for the info, TriCub.
Sounds like it's not an essential item then.
