Not that surprising. At the 6k service Tamworth Yamaha wound mine up so tight it was singing on the way home. Idiots. I wound a full turn off the adjusters when I got home.

If you're going to go tighter than recommended, make sure you check there's still a bit of slack through the entire suspension travel. I don't know about the XTR, but if the Ten is less than ~50mm on the sidestand, it goes tight with my weight pushing down on the pillion seat.

I just deal with the driveline shunt.
