I think that may be factory. If I get near my box-o-commander stuff I’ll verify.
So how you liking the low speed engagement spring? I’ve been very happy with mine.

I like it took out alot of the jerking when taking off.

I think around 16 or 1700. I’m out of town but will verify when I get back this afternoon or tomorrow

These are screenshots of before and after videos, both taken as soon as the machine registered 1mph...
Still very much in the jerky stages of beginning to move from a stop, the engagement seems to be the same to me... definitely aint in the 1600-1700 range like i would like

And actually if you take the Didgital tachs word for it the lower engagement spring is worse than the factory one

Couple of things: 1) at least on mine, I'm rolling before I register 1mph, 2) there is variance when I'm getting engagement - from 1400 to 1800 - really tough to keep it steady enough to be sure - you can feel it start to grab 3) when mine gets too jerky taking off, I sand the side of my belt, scotch brite the sheave faces and check that the flyweights are swinging freely, 4) I'm running the maverick belt (2700ish miles on it) which I believe is a hair wider than the commander belt and 5) here's a couple of videos I just made - it's on flat road and I'm rolling well before it shows 1mph (you can see this especially in the first vid):

Note: the occasional clunk you hear is the loading and unloading of the gearbox and drive line as the machine begins to outrun the speed that the primary is turning and then it re-engages through the helix. The clutch is engaged at all of those times.

If yours doesn't mimic this and your clutches are clean, belt good, etc, then I would stay that your spring is defective and you need to return it. You have stock clutches (no kit?)? What belt?
