1984 GS750ES

[Anonymous]

Hello,
First things first, this is an amazing site. I have just purchased an 84 GS750ES in fair condition and would like to find a repair manual for it before I start working on it. The problem is, this particular beast does not seem to exist. Any help would be greatly appreciated.
Thanks.

Well Jason, I ran into that same problem, only I was told I had an '85 GS750E. What I learned was that '83 was the last year they made the 750, in '84 they dropped it down to a 700. Don't go on just my word, I may be wrong, but I think you might have an '83 on your hands.

84 didn't come to the states, but 83, and 84 were 750's. 85 they went to 700. There are very few differences between the bikes, the 50cc difference is in the stroke of the engine, the stock jets are a little different, etc. You can get a manual here:
http://www.repairmanual.com/motorcycles/1983/62/6/5659 or keep an eye on ebay. Also, the manual for all 3 years is the same, except that the 700 has it's own section for the changes.

lhanscom : didn't they make the 750ES right up to 1987 ? Anyway, thanks a lot for that link - I ordered a manual right away

The USA-market bikes were affected by the "Harley-Davidson" protection tariff on bikes over 700cc for a few years after 1983. That is the reason for the capacity decrease by 50cc, so Luke is correct. Canadian-market, and other market bikes, were not so altered. My recollection is that the first of the GSXR-series bikes appeared in 1986, so the GS(X)750/700 was discontinued.

In Canada we got the GS750 up to and including 1986.

84 GS750ES

Thanks to everyone who replied, at least now I know the bike exists.
I do have another question, if anyone out there has done this before: I pulled the carbs out to rebuild/clean them and there will no longer be a factory airbox (don't ask) the plan is to use the individual pod/cone air filters. Has anyone done this?, if so what size jets seemed to work?

Many of us have done this, but my suggestion is that you purchase a jet kit. It will save you a lot of grief. BTW someone recently posted a site that had a great sell on kits. Try searching on jet kits for more information.

The org CV-carbs do not run well without the airbox since thay loose vacuum-buildup wich is essentiall to lift the throttles. A Jetkit could solve it but You dont gain much power. I ran my last bike, a -83 750, with a KN in the airbox, DynoJet st.1 and 4-1. You DO NOT want your engine to run lean in mixture. It is an aircooled engine and the risk of cracks in the head due to high combustiontemperature is a ruining find to do.

Weee - my manual arrived today - now I just gotta pick up a binder from work. Whenever I need to do any servicing I'll just photochopy the pages while at work, and then hop to it as soon as I'm home. If only somebody could sell me some of their spare time.
