Yeah, 10% (if they actually lose that much) is only 14-16 pounds so it’s not that critical.
Of course, being the anal retentive simple minded fool I am, I’d measure the springs after break in or maybe after dyno time or several hundred miles and shim them.
I don't know. I wouldn't call it a sickness....maybe just a "I wanna know" kinda thing. I'm just too dang lazy. Long as it still runs good, that's all I care about. lol
