Engineered wobble

[ktmsx350f]

Is this TSB going around for real ? Their is what looks like a dealer shared a tsb that basically said skidoo has an engineered wobble in the pdrive. I would really like to replace my XM stocker with a 850 but i don't want anything to do with belt issues some guys have had.
