Chain adjustment problem

[gsJack]

So I just got done doing a very close inspection on the chain there are absolutely no kinks there is Aston no signs of wear or rust on the chain. I looked closely at the rear sprocket to see it it was warped or if the teeth were bent . I could not find anything wrong with it at all .

Does anyone have any other advice on what I should check out next or and ideas on what's wrong?

It's kinky links causing your free play to vary as you described, just not enough to easily see yet.  How many miles on your 09 GSF?  Anyway, you should pull the front sprocket cover to have a look and make sure there are no surprises in there before ordering parts.  Maybe need chain and front sprocket, I've never replaced a rear sprocket but I'm a bit heavy with the chain lube, your needs may vary.

I've always used the clip type master links myself but opinions vary on that, your bike, your choice.  I changed the chain on my 97 GS the first time 9 months after I bought it new with 19k miles on the oem chain.

Sounds like it's time for a new chain! I ride year-round like GS Jack and have gone through a number of chains in 70,000 miles on my '07. I average about a year to a year-and-a-half for a chain. Don't go for the cheapest, even on an O-Ring or X-ring. The cheapest O-Ring chain I bought lasted less than 10,000 miles and I was very disappointed by it.

Good luck!

I have never had a chain last more than 10,000 miles.  I ride year round in Winter.  That will kill a chain.  All the salt, sand, dirt, schmutz...
