83 GS1100E chain and sprockets upgrade??

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

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

What's efficient for one rider isn't for another rider's requirements. Subtle tuning differences are possible with various combinations, not that important to me but for others it is.

One tooth on the front is equivalent of 3 on the back.

What Nessism said:encouragement:
I had the same issue. For myself going with 18/45 resulted in more useful gearing in the city and on cruising on the highway.

Lighter chain and sprockets matter they have an effect handling as things that spin don't like to turn.
Depending on the sprockets there will be a weight saving, in my situation it was 3lbs, 3lbs less spinning at high rpm. You may not notice but small details matter.
 
Thank you guys now the hunt for parts. According to Z1enterprises.com tech If I got with 18t 50t I need a 530- 118link chain in which they don't have the front sprocket or chain. I'm sure I'm also going need a spacer in the front sprocket
 
50T would be the wrong way. If you want to make first gear higher per your post above then you want less teeth on the back not more.... :)
