30mm is a tad on the tight side, 35mm minimum is better to avoid stretching.

Loose= good
tight= bad.

Cool, but the manual says 20-30mm?? But I recall you saying 30-35mm recently.

In any case, I think 30mm is on the low side in my case as it had it in gear...

EDIT: I just checked and its 30mm in neutral - although I have not checked it the whole way around, but it seems pretty consistent from what I have checked.

Yeah the manual says 25mm which is wrong.
35mm set it and forget it.

Get a fat mate to sit on your bike or lean over and pull the suspension down and check it,
you'll see that that 25mm is too tight even at mid stoke.
Chains tighten as the suspension compresses.

4000 hard road klm then 3000 track klm and ive NEVER re-adjusted the stock chain or the non Oring (I fitted for performance reasons.)

The more you adjust your chain, the more you stretch it.
By then its too late and you need a new one.
