17/50 530 sounds like a good way to go, then. Now is there somewhere that I can go to calculate the number of links I would need for that chain, or can I trouble you for the info? lol

Have a look at Z1 Enterprises, they have kits with the correct chain length for your bike.

why not a 16/45 combo...less chain...less weight...less cost.
and the Canadian with the mathematical skills is correct....
after laying a larger tooth count 530 over a smaller tooth count 630 as per discussion...they seem near the same diameter.

Go to http://www.gearingcommander.com/ .
Pick you bike model, the stock info will load.
You can change the pitch and sprocket sizes and have all your questions answered. There's even a way to calculate number of links IIRC.
FWIW, I went 18/47 and 114 links. I'm mostly city. Seems opposite with more highway-like gearing, but for me it's easier and more comfortable keeping up with traffic in this setup than stock.

When I did the conversion, I just ordered a 118 link chain and cut it down to the size I needed. Better to have too much then not enough. Don't want to add links.

So taking all of this advice into consideration, and checking the websites posted in the thread, I'm feeling fairly confident about a 17/46 530 setup. z1 has a 116 link x-ring chain which should only need one or two links removed, if I have figured correctly. Thanks for all of the input. I am really going to enjoy being a member of the site.

Before you do that, you do realize that 17/46 is taller gearing than the stock 15/42, right? If you are still after snappier acceleration this is going in the wrong direction.

Oops...lol I meant 16/47. Good catch, Mark.

I went 18/52 and the improvement in acceleration is very very nice. I'm a big fan of that combo.
2.88888888.9 is almost factory gearing(2.8).
i'm surprised you can feel any difference.

how many links is your chain?

Its pretty easy to feel, IMO. I'm 500rmp higher at 70mph than I was with stock gearing as well.

Your old gearing must have been taller than stock gearing for that much difference in rpm

I'm not sure what else to say. AFAIK the previous setup was all original but there's a difference of 500RPM at 70mph in 5th gear right before then right after I installed everything.

Wait, the '79 GS750 is 2.73 final, no?
15/42 would be 2.8
what was yours?
15/41 would be 2.73
what was yours?
15/41 would be 2.73

I didn't count but from the RPM and butt-dyno difference I'm banking on 15/41.

My '78 GS750E is 15/41 stock. Motorcyclist recommended a 15/43 combination, which is what I installed along with the 530 change conversion. You wouldn't want to go below 15 on the front sprocket.
