Hello!
How difficult is it to swap out the final drive of a 83a into a 80 gl1100?just bolt her in and go or are there any modifications?Or is the payoff worth the hassle?Regards,Johnyy

Fairly sure it's straight swap but not much difference. Specs of the gears really don't change much and the change maybe all be in the transmission..some one who really knows should be along soon.

80=3.091
83=3.100

not much diferance, but the 75-79=3.400
that might be enough change to be worth it.will it fit? They look the same, but I don't know for sure.

The 1000 final drive will not swap directly with the 1100 one.

The 80-81 models had ring/pinion teeth count of 34/11, giving a 3.091 ratio.

The 82-83 models had 31/10 teeth, for a 3.100 ratio.

Almost unmeasurable difference from the rpm to mph ratio for these bikes.

The reason for the change was to increase the size of the gear teeth, at the expense of a little more noise.

The 83 had gears set up for touring the freeways that was one of the main difference

so a swap would make a slight differece on the rpm.On the freeway, the benefits also seem to be negligable.Thank you all for the input.Regards,Johnyy
