adjusting chain off the stand

Yeah, me too. I was wishing I had AutoCad installed on my computer so I could lay it out and take measurements along the arc. Oh well.

Ok, duh, guess I never set my chain so tight I would notice it tightening up
off the stand.  Essentially the closer the swingarm bearings are to the
front sprocket the less the effect.  The arc around the sprocket is slightly
tighter vs. the arc around the swingarm bearings.  Learn something new
everyday ;-)

Dave, you are totally correct.

The issue is even more pronounced on a dirt bike with 12+ 
inches of rear suspension travel.  It's one reason they 
have rollers above and below the chain for this.

I have to say that like Bill, I like to adjust my GPZ (but 
not my dirt bikes) on the centerstand, but I've also 
learned how much slack there has to be vs when it's on the 
tires.  I also think it's important to have someone sit on 
the bike and check the slack if you're uncertain as that's 
going to be a good indication of how tight or loose it is.
