Chain Sprocket cover

[Headphase]

Just took mine off and it is full of some old spongey foam stuff, which would appear to be original.
I'm on an 80 gs750 , and had a 550 about 10 years ago, don't remember seeing any spongey foam cack on the sprocket cover on it.

Anyone care to elucidate?

Looks like expanding foam

Noise dampener. Nothing more and nothing less.

make that EX noise dampener

:-D

thanks, thats all I could think it could have been, either that or somebody washed the bike with a sponge and lost it in there

I run an aftermarket counter sprocket and also bought a chrome cover without the "lost sponge" and I hear alot more chain noise than before.:?
