Chain/sprocket replacement '78GS1000

[Guest]

I'm replacing what look to be the original chain and sprockets on my GS with a 630X96 DID O-ring and Sunstar front (15) and rear (I ordered 42; they sent a 40) steel sprockets.

Two questions: Anyone tried running a 40-tooth rear sprocket? I'm assuming it'll make the gearing a little taller. And (b) this'll be my first chain and sprocket replacement. Anyone have any golden, or merely sterling, advice about the process?

Thanks in advance,

Jack

Remove the front sprocket NUT before you take everything appart

I have run the taller gearing many years ago when I had a sports touring fairing and did a lot of interstate trips. It makes higway travel more relaxed as less rpm. I don't remember it improving or changing fuel economy in any noticeable way.
