Disgusting cover

So this is the cover over the front chain sprocket, where the shifter is. That's a foam lining and covered in tons of grease and dirt. Why foam? is that supposed to be there? Can i remove all of this crap? And can the cover be dipped in something that cleans really well?

Thanks in advance!

I believe the foam was supposed to be there as a noise suppressant.
Small putty knives for scraping the grease and then submerge it in Simple Green.
Some of the foam may crumble when cleaning. No big deal.

Mine was full of that and I figured it was some type grime accumulation from being flung off the chain.

next step, got the old front sprocket off. has side parts which i assume the space makes up for? from z1. but i cant get this new sprocket to slide on either. z1's web says it fits. do i need any of the parts that surround the old one?

No, you don't need any of the pictured parts.
Those two discs screwed to the old sprocket support the side plates of the chain as they round the front sprocket in an effort to reduce noise. You may still be able to get them from Suzuki, but not all chains are compatible with the factory style sprocket. The wider/taller side plates of some chains will bend and break the screws. Then the discs will rattle around making a helluva racket.

Seeing as you have already been to the Z1Enterprises site, you should be looking at doing their 530 chain conversion.

The 530 conversion is what im doing. this sprocket says on there that it fits the '78 GS1000. but i cant slide it on. z1 doesnt seem to have a phone number i can call.

This is what i bought:
