Mine didn't come set in the middle. Didn't change much when I centered initially. Mossyrocks- bottom them out counter clockwise, wind them up to clockwise, counting the clicks, then back out half the total number of clicks you found between bottom and top. That's your center. All bikes don't come centered. I don't know whether it's a dealership thing or a factory thing, but it only takes a minute to check. According to some learned folks here, every bike won't have the exact same number of clicks, though I wouldn't imagine the deviation to be much.
Madness- changes made the bike handle better, no doubt. A little jarring on notable road imperfections. Going to ride it for a few more days before deciding whether to adjust further. I have my front preload adjusted to two rings showing. Wondering if this is too much preload for a rider my size, particularly since my heli has moved my cg back a little..
