rear sprocket play?

I just noticed while cleaning my chain, the rear sprocket has a little give front to back where it mounts to the wheel. There's no side to side play, but if I pull the chain, the sprocket will move a hair (about 1/4 tooth) before the wheel moves. I clean/lube my chain fairly routinely & never noticed this. Bike has 25k miles on it, all street. RK chain & sprockets replaced 5K ago. Any takers?
Thanks,
Mike

I could be wrong and completely off but you MAY want to take a peak at your cush drive. They are there to ensure excessive force to the drive is not exceeded. Over time they can become a little rigid and reduce their ability do do so.

The cush drive is it.

Pat- 2007 DL650A was ridden to all 48 contiguous states. 2012 DL650A is just getting started.

Yep, you have your answer. If it is excessive...which varies by opinion on how much, you can do one of two things. Buy new cush drive rubbers and count the months or years till it reoccurs or you can shim it. Some will poop on the shimming idea but that is exactly what I did with a Vee...which is harder on the cush drive due to more power in the engine.

To shim, I used 1 inch long +/- pieces of 2.125 mountain bicycle innner tubes. You are cutting across the tube to make 1 inch wide rubber bands. I may be off on the 1 inch but you shim the hieght of the internal nubs. This extra rubber thickness was perfect and returned my cush drive to normal play. I believe the next time I mount a tire...around 70,000 mile mark on my Vee, I will buy new rubbers. The play first showed up in mine around 20,000 miles and I have shimmed it to this point.

It would be good for a high mileage rider to check out these urethane cush drive dampers and see if they work well in a strom.

Urethane should be a great replacement. The bikes listed there use different cush rubbers from the Stroms though.

Pat- 2007 DL650A was ridden to all 48 contiguous states. 2012 DL650A is just getting started.

Thanks for all the replies. I'm getting ready to put on a new rear tire soon. Will replace the absorbers & check the bearings while it's apart.

Urethane will be denser, heavier, more rigid and less flexible than the oem cush rubbers. They won't dampen as well and will transmit more shock. This would be less of a problem for the lower powered 650 than the 1k.
