Guys,

I'm in the process of swapping the head on my 450, and as such have the chain off as part of the engine removal. While cleaning the frame the other day I noticed that the rear sprocket has some back-and-forth play in it, maybe 1/8 of an inch. Is that normal or is something messed up?

If your saying that you can rotate the sprocket back and forth on the hub....Dude, your bolts are loose! Pry back the bolt safety locks and try tightening them up! Thats the only way I can see that the sprocket would turn on the hub by hand.

Anyone else got an idea?

That sounds about right to me. It's gonna have to come apart for inspection, for safety sake, plus you'll learn something new to boot.

The snap ring could be worn, the nuts/pins could be loose, or the internal rubber cushions could have failed after 40 years... In any case, disassembly and verification of the specific problem is necessary....Then fix it!..... Steve

So it sounds like I'll be taking it apart soon! Thanks for the replies, it didn't seem like it should be that loose.
