Chain / Sprocket 83 GS 750ES

[Ward 83750es]

I need to replace the chain and sprockets on my 83 GS 750ES. Has anyone done this? If so did you use the stock set up or change it, if so how did it work out for you? Did anyone find a good deal on the parts? I live in British Columbia Canada where we have well built twisty mountain roads for the most part.

i went bigger front and rear,
bigger front will lower the rpms,and give faster top end
bigger rear will give more power ,lower top speed,but pull more
small front will increase rpms faster,and be quicker
i havent rode mine yet but i have done it before,it depends on if you want fast top speed or more power, and fun "more" shifting
ebay,has a lot of good deals on front and rear, you might want a new chain while your at it so the wore out chain doesnt ruin the new sprockets
also dennis kirk isnt bad on some prices,maybe bike bandit if there are specials

I'm assuming you have the 630 set up yet, since you need to change everything, why not convert to the 530 set up at this time.

Since I know ward from the BC Classics site http://www.bcclassicmotorcycleclub.c...k=click&bid=12 I know he has a 83 GS750ES with a 530 chain stock.I have a set of sprocets and chain off one of my parts bikes one my 85.One up in front(16 vs 15 stock)and 5 down rear(40 vs 45 stock)I like it,revs slower at highway speeds but still has plenty of go.

I think the stock gearing on those bikes is just about perfect. I might be tempted to add a couple of teeth to the rear if anything as you need to rev that engine to get it to perform in my experience....

I wouldn't go smaller on the front sprocket as you will wear the swingarm protector out quite quickly & risk chain touching the swingarm.

I did use a 530. RK X-link 14 front 44 rear. I find that the one tooth larger rear sprocket changed things more than I thought it would. I find the front end will lift now if I feather the clutch a tad. In my world the perfect wheelie is about 3 to 4 inches.
It turns out my original factory O-ring chain from 29 years and 26000 Km ago was stretched around 2 links worth.
It is amazing how much the new set up and chain tighten up the whole riding experiance!

I find my current 14 / 44 set up gives the bike a nice feel, the previous set up was 14 / 43. This could be because the chain is not all slack and stretched like my old one, or the additional tooth on the rear bumps up the bottom end ever so slightly. I am quite happy with the change. Cost me about $225.00 CDN and $50.00 for a very talented and cool BCCMCC member to install it for me.

Agreed. The only exception was my DL1000 Vstrom where a one-tooth smaller front sprocket worked the first 5 gears well and made more use out of he 6th gear (overdrive). Threw out my speedometer readings by 10% however.

sprockets cannot change the speedometer, the speed comes from the front wheel, it will make rpms seem different though
now a different size tire can, 130/90/16 to a 100/60/16 since the tire will rotate different it might be off a pinch
