SOURCE: what is the best carb set for this year gsxr

Pull out the slide then lower the clip on the jet needle one notch. Then try two notches. This will richen the mid range response. Give this a try before trashing the carbs.

Go to the site below and you can download a free service manual PDF. The one you want is 47th from the top of the Suzuki list. Yes, I know that it is for '93 to '95 models. It is the closest I could come to '89 and 90% of the data doesn't change and it is free. For an exact match Google " service manuals suzuki " or go to www.repairmanuals.com
Also try your local library. Often guys will donate manuals to the library.

SOURCE: How and where do you adjust the synch on 1986 gsxr

I can help with this.
On the earliest models they had slide type carburettors. This is to say that the slides were actuated by the throttle cable acting on a linkage that physically lifts the slides in the carburettors. This type of carburettor has its balance(syncronization) adjusters under the caps on top of the carburettors.(the cap isn't round & has 3 screws in it)
Number three carburettor is fixed & dosn't get adjusted.

You'll have to put the bike next to a bench & attatch a long piece of fuel hose from the tank to the fuel hose on the carburettors.You can join the two pipes together using a short piece of hose that snuggly fits on the outside or inside of the two hoses. You can also join them with a suitable shirt piece of metal pipe,or what is called here in Australia a P3 barb.These are available from tool suppliers that supply air compressor hoses & fittings.
(I made a remote tank from an old lawnmower petrol tank,a long piece of hose & mounted it on a tall stand.Under it I have a tray with all my different adaptors in it.)

You adjust number 2 cylinder to the same vacume reading as number 3 cylinder first.
Now adjust number 1 cylinder to the same vacume reading as number 2 cylinder.
Next adjust number 4 cylinder to the same vacume reading as number 3 cylinder.
Recheck that they are all the same & your done.
The adjusters are of the screw & locknut(8mm)type.
You can struggle with an 8 mm ring spanner & a flat bladed screwdriver,buy an adjusting tool(genuine, or non-genuine from a bike shop) or make one.

To make one you weld a bar onto the side(at the top)of an 8mm extended quarter inch drive socket.Then find a long small screwdriver that will fit down the hole.

After you make each adjustment,stop the engine & open the throttle wide open & release a couple of times.(This seats the slide).After diong this re-start the engine & re-check your adjustment.
I place a fan blowing on the engine to help control the engine temperature as the adjustment can be a bit of a fiddle.

I prefer to use mercuary type vacume guages as they dont go out of calibration.

If you are using dial type guages check that they are all reading the same by checking them all one by one on the same cylinder.
Some Suzukis' have a pipe (covered with a black rubber stopper) at the top of each carburettor(at the front) & others have an allen screw on the cylinder in front of the carburettor manifold rubber.
If yours has the allen screw you will also need adaptors that screw into the hole once the allen screw is removed.

If you bike has diaphram type carburettors on it(you'll be able to recognise this by the top caps of the carburettors being black & roundish in shape & held in place by 4 screws), the adjusting screws are between each carburettor & are the spring loaded type.
The adjusters are located in-between each pair of carburettors visable from the top.
These are easier to adjust as there is no lock nut to struggle with & all you need to turn the adjusting screws is a long (flat or phillips)screwdriver.
Again, balance the center two first,then the left pair then the right pair.

This procedure is applicable to all in line 4 cylinder motorcycles (even most fuel injected ones.

SOURCE: need fuel and vacuum line info

there should only 2 lines from the fuel tap, one for fuel, and the other for vacume, the smaller diameter hose is the vacume, and the larger hose is fuel. fuel hose will go to carby, and the vacume hose to the carby inlet manifold.

Bad ignition coil. You can try to find the OHM specs and test it but that is what happens when you have a failing coil.

1991 GSXR 750 cutting on low revs


run a can of Seaforam in the tank..purchase from Autozone put in 1/3 to two gallons gas drive it around for at least 10 miles to insure it cleans out the whole carb system.if that doesnt work, check all carb hose fittings when bike is at idle spray some Chemtool B-12 ( also at Autozone) around the carb hoses and manifolds..if idle increses thats your problem. Caution: chemtool is very toxic wear gloves and a mask.

If its a slow leak. Yes Normal. If its pouring out. you might want to check your fuel lines. If it continues to come out you should replace your gas lines immediately.
