'79 GS750 - 530 conversion

[blowerbike]

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?

[mattfeet]

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

[mattfeet]

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?

[blowerbike]

15/42 would be 2.8
what was yours?

15/41 would be 2.73

[mattfeet]

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.
