83 GS1100E chain and sprockets upgrade??

[P09luis]

What's everyone running on their GS1100E? Going with a 530 chain 16t front sprocket and stock rear sprocket. Any other configuration you guys think is better. No I'm not drag racing or ride with a passenger.

Stock is 15T front & 42T rear. 2.80 ratio

15T + 3T = 18T front (you need this size in order to match the original sprocket diameter)

2.8 x 18 = 50T rear sprocket. If you want lower RPM then you can go to a lower tooth count.

1100E uses 96 links in 630. 96 x .75" (link length) = 72" long chain. A 530 chain has 5/8" between links. 72" x 8/5 = 115.2 (use a 116 link chain in 530)
1100ES uses 98 links in 630

Mine is 18 on the front and 50 on the rear. 120 links of 530 chain and I cut off 4 if memory serves.

530 18/50 and I think the chain was 119links. I have a 82 gs1100e with a 84 gs1150 rear swing arm.

If you are wanting to keep the stock gearing but switch to 530 then 17/48 is what you want. It will not change the gearing.
The 530 - 17 tooth sprocket is the same diameter as the 630 - 15 tooth sprocket

I have 18/48 and the bike pulls fine.

[Nessism]

The 530 - 17 tooth sprocket is the same diameter as the 630 - 15 tooth sprocket

This is incorrect.

Pitch diameter for 630 15T sprocket is 92mm
Pitch diameter for 530 17T sprocket is 86mm
Pitch diameter for 530 18T sprocket is 91mm

This is incorrect.

Pitch diameter for 630 15T sprocket is 92mm
Pitch diameter for 530 17T sprocket is 86mm
Pitch diameter for 530 18T sprocket is 91mm

I've seen both recommended but I went with 18t.

Best practice is to match the front sprocket size. Never smaller.

I've a bit more hp/torque with a '84 1150efe plus additional boost from headers and rs36 flatslides. 18t front, 45t rear to lower rpm.

depends on what you're goals are. I've come across quite a few people running 17 and 16 without issues.

[Nessism]

What goals would drive someone to want to smaller and less efficient front sprocket?

[P09luis]

In my case I feel like when in 1st gear within in seconds I need to be in 2nd gear I kind of want to be able to use 1st gear a little longer before I go to next gear. Not sure if I'm explaining myself well.

A 47T or 46T rear sprocket will help out with this situation, it will also give you less rpm on the highway.

So keep front sprocket stock? Also ill go to 530 chain since is lighter and again I don't race my bike.
