Well I'm on e of the new Val riders, but I've noticed several others join lately so I thought I'd suggest looking closely at your shock bushings before you disassemble the final drive. Three of the four were really bad and the fourth was marginal. I'm replacing all, but this is delaying reassembly till the parts arrive. Not A huge deal with the cr@ppy weather this week, but for the southern riders that may not be the case.
PS splines looked perfect.
