Part numbers 83-85 GS 750/700

[Smokinapankake]

Howdy folks;
Lookin for the Suzuki part numbers for front and rear sprockets off a GS750 or 700 from 83-85. Reason I ask is that I'm fixin to order a chain and some sprockets for my 84 Katana (which is basically the same as the above mentioned models). I'm kind of debating about keeping it all stock, versus swapping for newer Katana (GSX600/750F) forks/wheels/brakes.

SO, with that said, the part numbers I have are as such:
14t front sprocket: 97511-47100
43t rear sprocket: 64511-08A00
Mind you, the numbers I have are Genuine Suzuki part numbers, listed in the Suzuki part fiche. To answer my question your numbers must also be Genuine Suzuki part numbers, pulled out of the factory parts microfiche, not Bikebandit or somewhere else. Further complicating this is the fact that I can't simply go to Bikebandit and compare their numbers between models, as they don't list a 1984 GSX 750SE.

Also, my owners manual calls out this chain:
DID 50V or Takasago RK50G0, 114 links. I believe this is a 530 o-ring chain. Can anyone verify this for me?

Basically, I'm trying to decide whether or not I can simply order parts to fit an 83-85 750/700 and mount them up successfully on my 84 GSX 750SE.

My questions arise from a discrepancy between the 83-85 750/700 front brake calipers being different from my 84 Katana 750 calipers. I assumed they were basically the same bike, and they are, but I need front brake pads off an 85 GS550ES, and rear pads off an 85 GS700.

Oh the joys of owning a foreign market motorcycle.....

Any help is super appreciated. Clear as mud?

So I went out and took some measurements off my existing chain:

7/8" width at the outer plates
3/8" width of rollers, i.e., inside of inner plates
5/8" spacing between pins, or pin C-T-C (Center to center).
According to my Dennis Kirk catalog, this denotes a 530 chain.

For the record, it's running 43t rear sprocket and 14t front.

I counted 114 pins, so does this mean 114 links? Probably because I can't imagine a chain having 228 links, or alternatively 57 links.

With all that said, should I decide to alter gearing to reduce RPM at highway speeds (60-85 MPH), would it be better to increase front tooth count, reduce rear tooth count, or some combination of both?
Not saying I will, I realize these motors were made to run, just curious as to what you far more educated patrons prefer....

114 links would have to be 530. Regarding the gearing, going up one tooth on the front sprocket is a cheap and easy change to reduce rpm on the freeway – about 300 rpm at freeway speeds is typical. If you gear the bike taller than this, getting underway from a stop will require a more significant amount of clutch slippage than stock.

I’m not familiar with your bike so not sure about interchangeability of sprockets between yours and the US models. Factory parts tend to be quite expensive compared to aftermarket when it comes to things like sprockets and chains. If you go the JT’s web site you can find info on the measurement of the various sprockets they make – measure yours first. This should help you figure out interchangeability.

Good luck and hope this helps.

Thanks Ed, will look into it further before spending any real dough.
I'm fairly confident as they share engines, wheels, and drivetrains.
But will do my research first definitely.

That is to say the 83-85 750E/ES/700E/ES and my 84 750SE....

The only difference is the 700 had a 45 tooth rear sprocket.

JT Sprockets website has detailed drawings of their sprockets that lets you compare bolt patterns, center holes, spline specs, and anything else you might need that will help. You'll find GSX-R and GSF sprockets that will let you do 520 conversions if you wanted to go that far. You can find GSX-R and GSF sprockets in 530 sizes as well. Just gives you a few more options.

Just looked at the JT site, Thank you both Ed and Billy, they are the same sprockets.

Will be ordering soon.

Thanks again!

P.S. How would I go about comparing in order to determine what sprockets to get to fit a 520 chain? And what is the advantage of 520 vs. 530?

520 is lighter and you lose a little less hp to the rear wheel. It's usually more of a way around clearance issues from running wider than stock wheels. If you wanted to do it just look at the info at JT's site to see which GSX-R and Katana 600 models use the same sprockets. Then go to Vortex Sprockets site and see the 520 conversions for those models to use on your GS. I think JT offers 520 conversions too.

HI Mr. Smokinapancake,

I've found that http://www.cmsnl.com (Netherlands) has many parts fiches for non-USA markets.

http://www.cmsnl.com/suzuki-gsx750_model13694/

Perhaps it will help in your research.


Thank you for your indulgence,

BassCliff

... your numbers must also be Genuine Suzuki part numbers, pulled out of the factory parts microfiche, not Bikebandit or somewhere else.

By the way, I have only notice Bike Bandit using their own numbering system for parts. Many of us go to the Alpha Sports page to find Suzuki part numbers because they not only use actual Suzuki numbers, when you click on the number to get the price, it will also lead you to any superceeded part numbers that might be there. Unfortunately, they also happen to be one of the most expensive part suppliers, so we just shop for part numbers.

BassCliff,

Thanks for the reference, I already had CMSNL bookmarked. If you (or anyone else) are interested, here is the specific page link: http://www.cmsnl.com/suzuki-gsx750-1984-se_model13720/partslist/

Steve,

CMSNL also links to a listing of all the models that particular part number is common to.

Thanks for all your input; that's what makes this such a great forum. In the name of ease (lazy) I'll probably just stick with the standard issue 530 stuff.
