Hello! New here, not finding the information anywhere yet.

I just picked this one up off of Craigslist for $275 with a nice Judy fork and a spare set of rims. Can't complain.
Went to ride it and I found that the rear pivot allows lateral as well as vertical movement, and that seemed wrong to me.
So I look at the assembly. There's a pinch bolt on each side of the swingarm to attach to a pivot bushing.
Does anyone have torque or adjustment specs for the pivot and the pinch bolts?
I understand this isn't the most popular model ever, and I'm not trying to win the X-games with it. I'd just like to take it for a ride without hurting the bike or myself.
This bike was just too cool to pass up!
