End play on rear wheel

I have an 03 Lt. When on the center stand I can mark the bottom center
of the tire and get about two inches of play, moving it like the bike is in
forward motion no side to side play. Is this normal
Thanks Jon L.

There was a thread a while back with the same question. Being the curious type I went and measured mine and seems that marking the sidewall of the tire the dimension was in the vicinity of 2.5".
I would say your findings are "normal".

Thanks Duane.
The reason I checked was I felt a thump when hitting bumps on the road.
I assumed the tire was lifting off the road surface enough to allow the play
to be felt. Jon L.

Drive line lash

With the bike on the centerstand and the transmission in gear rotation of the rear wheel will occur to the point where the lash in the drive line is taken up, and engine compression stops the turning.
This will probably vary a little bit depending on what gear is selected.
Gear wear, improper shimming of the pinion gear in the final drive, and bearing wear in the tranny could all contribute to excess drive line lash; however the amount you describe sounds normal.
A certain about of "slop" in the gears is engineered into the transmission. Lots of factors influence transmission performance but a really "tight" gearbox would be a hard shifter so a limited amount of play is engineered in to improve shifting behavior. This transmission "slop" and normal gear spacing in the final drive and engine driveline add together to create the "free play" you are noticing at the rear wheel.

Are you running the OEM shocks? Have you tried adjusting the rear shock?

Thanks for all the help.
The shock is stock and I only notice this when
riding two up. I'll try adjustments. Thanks guys
