Will start and idle if only if it is choked. unchoked it will barely start. both ways it will stall the moment i try to turn the throttle. all spark plugs are getting a spark. fuel is good.if I spary starter fluid into the air box it revs right up. it is as if its not getting enough fuel to do anything more than idle. im thinking the fuel pump may have gone. if so... can you provide me with the pumps specs so I can find a comparable one to the oem part.
That bike has 4) 36mm Mikuni carbs. Most likely they are stopped up. If you have been running U.S. Fuel with ethanol added this is not good for the carbs. Or most likely it was sitting for the winter, and the carbs got stopped up. If you have the carbs cleaned out, this will fix your problem. Keep me updated, and good luck. P.S. if a shop does this work it will be expensive, its not a hard job just time consuming.

Hi and welcome to FixYa,
On most Suzukis with fuel pump that I have worked on, the wiring would be:
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

Do not spray starter fluid in the bike. You definately seem to have a fuel problem. The right thing to do is test for fuel pressure before injectors and see what you have. Also you want to test the bike with the air box on. Do you have an f.i. light on, if so pull the code. (you need a paperclip to do so). If you decide you need injectors I would pick a set up off ebay. They sometimes sell them with the throttle bodies and they only run about a 100 dollars.

When you are on the bike and riding do you still have the choke out? And stop spraying starter fluid into the carbs..bad bad bad.... bikes start with out that stuff and if you need it then something is wrong.. your gonna mess something up doing that....let me know about the choke and we will go from [email protected]

Please check your exhaust pipe or the silencer. It must have been chocked with carbon and you have to remove the carbon deposit to run your motorcycle.
Also clean your fuel tank as it could have dust deposits at the bottom chocking the fuel flow once it is in running condition.
Please change the spark plug as recommended after covering a distance specified.

the problem with the rubber was close but on the gs450 there is a metal insert that even if the rubber was rotted away the metal seals aginst the head so it cant leak. the problem is on the gs 450 suzuki used a cheap throttle cable that kinks behind the gas tank and kinks at the bend to the crabs under the set and the throttle system is a pull only not a dual cable pull push to always close the throttle. if you start the bike a wiggle the bend in the cable that comes out from the twist grip you will see it changes the idle. with either your finger or a screw driver and push the plate down on the carbs that the cable connects too. if the idle drops this conforms your problem. order a new cable from dennis kirk they have the revised one that has metal adjustment screw and metal clip in. better jacket casing as well.
