I forgot to add that because my bike's rear is lowered I worry about the change in static position in the arc with respect to belt tension moving throughout the arc. If the swingarm is pointing exactly 90-degrees from the front pulley then the belt is at its tightest in its arc range. Above and below 90 its arc effectively loosens the tension. So as my rear suspension acts it will cause my belt to become tighter at moments and looser at others. I take that into account by targeting 7mm ~ 8mm as my 'on-the-kickstand' number. Its not enough to snap belt off the line at WOT unless I really f-up.

All of those numbers are still between .25 and. 33 inch so I like to use mm and skinny it up. I worry about looseness at the ends of the travel range if I'm for example leaned into a corner and go WOT on exit, which snaps-up any slack. Same for standing start WOT it squats down even lower real quick even with the Eibach 1000. So far so good.

From this picture of yours it does not look like it is lowered.
