    I have a 1994 GSX750F and have replaced the carbs. I was told the carbs off a GS650 would do the job but the problem is I dont know which hose goes where (fuel tank to carb etc) Would be grateful for any advice.

    As generally, you'll find 1 larger connector in the cnetrheight of the carburettors. This is the fuel supply from the tank. You can have 4 small connection at the bottom of the carbs, those are purge outlets, must not be connected, or connect them all apart to a hose going down the back of the engine. You' can find 1 connection at the engine side of carb 3 ( beginning from lefft, this is to connect an pressure fuelcock. And, you'll find a smaller connectiin in the upper middle of the carb height on carb 2, this is the vent for the fuel chambers in the bowls. Connect just a hose going down at the back of the engine...t

I have an 89 Katana and don't know where the two vacuum lines on the top of the carbs go

    The one at the 'engine side' of carb 3 is the depressure for the automatic fuelcock. the connector on carb 2 at airfilter side is just the vent for the float chambers...

I have the connection shematics.
I'll try to explain, if needed send me your mail address, I'll send you a drawing.
First, the elements and their amount:
- 1 rollover valve, 2 straight connections.
- 1 Canister, 2 connections at the top, 1 outlet at the bottom
- 2 5-way connectors
- 4 Vacuum control valves, 2 connections at the top, 1 at the bottom
- 1 fuel tank, 3 connections, 1 is the surge hose connection, 2 others on the fuel ****: 1 fuel hose, 1 vacuum hose
- 4 carburettors: Seen from the back: 1 fuel inlet on a common ramp at the back, 1 vacuum connection between the two center carbs, 2 ventilation hoses at the outside of both center carbs, 4 purge hoses, 1 on the air filter side of each carb ( at the center of each external carbs ), 1 connector on the most left carb at the front bottom.

Now, the connections:
- 1 hose from the fuel tank surge hose connection to the roll-over valve, air must go from the tank trough the roll-over valve
- 1 hose from the roll over valve to the center upper connection of the canister.
- 1 hose from the second upper outlet of the canister to a 5-way connector.
- The third connection of the canister must stay free ( fresh air inlet )
- 4 hoses from this 5 way connector, 1 hose to each vacuum control valve at the upper 'side' connection
- 1 hose from each upper center connection of each vacuum control valve to each carburettor purge connections.
- The bottom connections of each vacuum control valve must be connected to the other 5-way connector.
- The main gallery of this 5-way connector must then be connected to the bottom front connection on the left carb.

I hope you've understood the explanation and you are helped.
The 1989 model is different ( it has a canister with 4 connections and only 2 control valves )

Suzuki 750 Katana Hoses?


Hi, Alexander always check your service manual for proper routing, PVC type valves, and vent lines allow the following components to breathe freely:
1. Gas caps.
2. Gas tanks.
3. Carburetors.
4. Lead acid batteries.
5. Evap canisters.
6. Engine crankcases.
7. Rocker boxes.
8. Transmissions.
Numbers 2-3-4 have vent lines that are routed directly to the ground usually 2" below the lowest part of the frame and loosely secured with stanchions/stand-offs or tie wraps. These lines have minimal curves and their ends do not attach to anything "WARNING" these lines should be inspected at every maintenance service for end clogging or closure pinching or kinking or missing altogether.
Failure to properly inspect and maintain vent lines may lead to:
1. Gas tank implosion.
2. Improper float levels.
3. Batteries exploding.
4. Blown crankcase and transmission seals.
5. Air cleaner oil saturation.

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.

Really need help with hose diagram


If you see here number 14 is where you attach the fuel pipes.Number 6 are the carb's overflow pipes which you drive them through steady route towards the ground.They don't attach anywhere.Number 16 is the vacuum hose which goes behind the fuel **** assy (number 1).Check out those diagrams and see if you can find any help.

Vacuum line not connected correctly


ok fuel fill lines are the 2 lines between carbs 1 n 2 and 3 n 4 toward the rear of the bike the 2 hoses coming out just in front of them are float bowl overflows that just get criss crossed over the carbs and ran thru the little holders on the frame. the only vacuum line is coming out of the side of carb 4, this line goes to the nipple on the petcock facing away from the knob. as for the fill lines the 1 between 1 n 2 goes to the nipple facing the rear of the bike and 3 n 4 goes to the 1 facing the front of the bike. hope this helps here is a link for a free service manual download. http://www.files.michaelmcmahon.org/1988-1997-GSX600-750-1100F-R.pdf try using www.katriders.com it is a lot more helpful than this site for katana issues.
