Top 20 1994 Suzuki GSX-R 750 WR Questions & Answers

I owned this one for 20 years and have never heard of this type of problem.

have you checked the carbs are clean and all seals are good ? floats float if you put in a jar of fuel ?

Lots of things could cause this! Oil being over full can effect it this way but would have to be really high. You would also notice a lot of smoking if this was the reason. Carbs not being Sync'd correctly will cause this. Main jets in carb plugged or wrong size. Float level off can cause this. Timing off can cause this. Most likely the problem is in the carburation. Hope this helped!

10w40 semi synthetic of fully sinthetic

u need to adjust the free play in the clutch lever

Some manufacturers (I'm more familiar with Yamaha than Suzuki) used a starter button that had 2 sets of contacts...one for the headlight, one for the starter circuit. The idea being to save battery power while cranking,,,,so as you pushed in the button, first it opened the headlight contacts, killing the headlight. As you pushed in further, it closed the starter circuit contacts cranking the starter.
Problem is over time...dirt etc gets in behind the button, so when you let your finger off, the starter contacts reopened, but the headlight contacts don[t close again....so no headlight!

Key off, Try spraying some Wd40 around the button to flush out any crud and work the button in and out letting it snap out several times.
Then retry key to see if headlight is back.

Lift the seat. You will find a bolt screw. remove carefully and the tank should be able to be pulled. If you have any petrol in the tank be carefully as it may become unbalanced with the fuel slopping around.

Hello
Having owned this (mine was a 91) model and knowing allot of Suzuki owners over the years the problem here is the fuel valve (called a Petcock valve) is defective, they sick, the reason is that the valve is operated by engine vacuum, so it only delivers fuel when the engine is cranking over or running, the only exception to this is the so called Prime position marked with a "P" on the valve. The hose consist two small vacuum lines from the engine that operate the valve in the run and reserve position and the large line is the fuel delivery hose to the engine. My advice is to mark the lines with tape, remove the fuel tank and replace the fuel petcock valve with a new one, this will also eleminate the other nasty problem this valve has, the rubber O ring fails and it leaks fuel all over the engine fairings and runs the paint, this happened to my bike.

you say you cleaned the carbs, but did you pull and clean the jets ? they are very very tiny holes, and take like nothing to plug them. pull the jets and run a wire from a wire brush thru them, should start for you now

Go to the website below. It looks like they have it in stock. Also, you might want to Google motorcycle salvage suzuki and see if you can get a good used one. Please rate my answer. Thanks.

This could be a number of things like bad oil or just something simple as adjusting the idle screw. that is where i would start.

Your motorcycle has a two position switch in the starter button. When you push the button in halfway the headlight turns off to give all the electricity to the starter. Push the button in all the way and the starter solenoid activates. You probably just need to clean or replace the starter button/switch. If the button will not work after cleaning, the button is usually only sold with the right switch assembly. You will have to replace the whole right switch assembly.

check to see if the switch at the kick stand is not stuck> this tells the bike the stand is up and will allow you to engague it in gear

dont matter if it fitz wearit--I use no filter on my 80 yama 250-itz just a motorbike

sounds like your coilis not getting power .1-4 use one coil 2-3 use another. check connections at that coil then check coil to see if its not cracked and arcing to frame

u cant but the library sec629 may hav one or something close-*** bikes r pretty similar--clymer sells great manuals on just about every year and make

The head is being held on by the gasket.
If all of the bolts are off gently hit the head with a rubber mallet. Or gently tap a thin putty knife between the head and the jug to seperate the two be very careful not to scratch either surface. Gentle is the key word
lots of luck. If you find this helpful please leave a good rating Thanks, Jack

Balance the bike to a level position while looking at the oil glass, with the engine off. Bottom of glass is low, top of glass is full, no oil in glass, top it off, not quite a qt. Use high quality motor cycle full synthetic 5w 30. Hope this helps.

you will need to undo the bottom hex , and the whole damper spring come out together

It wont cause damage unless the bike is started , so you must drain the oil and replace before running the engine, it may also need an air filter element.
You then need to fix the cause, which is likely the fuel tap which is vacumn opperated to only work when the engine runs.
