i can only get it to start on starting fluid. then once its warm (after revin for a while because it wont idle until its warm either) then i can shut it off, and am able to start it up again without fluid. only once its warm.
EDIT: Its a 97 E
let it live inside your house were its warm, so you wont have to cold start it ever. 8)
Dumb question but are you using the choke? Have you re-jetted?

I dont mean cold like winter cold. I just meant hasnt been running. its at my school shop right now inside with heating.
And yes i use choke no i have not rejetted. and no its not a dumb question, and while rejetting may help, the bike should still be able to start stock. Suzuki didnt make bike thinking "you know what, lets make this model of our motorcycles to where you have to buy new jets to get it to start."
Theres plenty of GSs out there that havent been rejetted and still start.
Fuel, air, spark, compression.
All else being in order, it can help to open and close the throttle a few times to "flood" the bike a bit before first attempting to start. Of course, use the choke or enrichment at full on. You might wanna dump that straight 50 weight oil ;-)
A weak spark such as wrong or shot sparkplug or weak coil can do that too. Old funky gas can lead to that too. Low compression also. As can a leak at the carb mount gaskets.

well opening and closeing the throttle doesnt flood the engine, or do anything at all if its not turning. the throttle just opens the throttle plate which allows increased airflow which picks up more fuel, but the air only flows if the engine is turning. I ordered some new plugs the other day but got the wrong size. so once i get the right ones ill see it helps.
My GS was very hard to start when cold. I did everything I could think of. New fuel lines, petcock, carb overhaul, airfilter, battery etc.
Then I changed my sparkplugs. They were a little dark, but did'nt really look like they needed replacement, but I already bought some new ones, so I changed them anyway.
Now it's starts immedieatly (argh, sorry for spelling ;) )
once it's warm and running, does the choke change the idle? What I'm getting at is..... does the choke actually work? And once warm, is the idle in the 1500-2000 RPM range with no choke?
'05 and still stock except for the battery. I found that on the original battery, I started it with a touch of throttle, and after getting a new one, I was having a HARDER time starting.
I simply stopped using throttle at all during cold startup. Just choke, clutch, & starter, and it starts turning over pretty well. After that its just a matter of babysitting the choke and revs for a few seconds.
Barring other problems like gas line issues, vacuum line, air filter and intake/exhaust leaks most problems in cold weather are due to the lean jetting from the factory.
Jets +1 all around will cover most if not all.
Cool.
Buddha.
yea i have an 04 and stock fuel setup won't allow you to tinker with throttle on cold startup it will just die. here's what you do, put 1 washer on each needle, and it will be perfect, that's the only thing i've done to my 04 and it's awesome. for now, just start the bike on full choke, and let it sit at like 4k for a minute or so, it will then run perfectly.
Turning the trottle on the GS before starting it does nothing, all the trottle is doing is opening a valve, not releasing fuel directly.

Yea the choke works
And Bluesmudge, i know, i told him that but i dont know if he read it.
Sorry, I posted to this thread from my cell phone and didn't see that there was another page so I didn't see most of the posts.

Yep; he read it; twice. I gotta admit, I have not taken my carbs aprt, yet. They are pure stock. On my other carbed bike, turning the throttle grip squirts a good shot of fuel into the intake. It is a very lean machine and I was wondering about the merit of using washers as shims for the stock needles.
prs
Choke on and run for 1 min @3-4K and then its ready to ride off in winter. And 30 seconds in summer = proper jetting for the idle and low throttle opening throttle positions.
If everything is right and clean and no leaks and what not but your bike isn't working as above, it needs to get some help with its jetting. Seriously they sent it out from the factory just a hair anaemic. If you've had some wear and floats are a little high (common on 89-00) etc, you can be nearly spot on with the original jets ... else you're gonna have to rejet and adjust it back to the spot where it likes it.
Cool.
Buddha.
you mentioned using starting fluid. I wonder if you have a air filter ?
without a filter it'll be lean.
Yea, i got a filter.
^^^
is it a stock filter?
i wouldnt use starter fluid it drys out the cylinders and is not good to use
its actually carb cleaner. i just use it for starter fluid if i have to. and its not technically stock air filter but OEM replacement so kinda yea its stock.
The carb cleaner will degrease the rings and cylinder bore even worse than starting fluid (at least most starting ethers have a lube in them). If you have a chainsaw or week wacker, try putting a little 2 cycle fuel mix in a spritz bottle and see if that will stard her. You may need a compression test without and then with a dose of motor oil in the cylinder to see the valves or rings are leaking too badly. Just check the easy stuff first though.

Compression is fine, maybe ill just use a spray bottle of regular gas. think im gonna be overhauling and rebuilding the engine tanyway his winter so it should be fine after that. just gonna have to use the spray bottle until then i guess. thanks for the idea.
My bike is finicky to cold start if I don't let it prime for several minutes especially after not being run for several days. I get the feeling that gravity feed isn't all that great where intial prime is concerned, on dry carbs. But i could be wrong.
so when you let it prime for a few minuetes it works ok? ill try that. and for anyone thinking im crazy to go until winter on a spray starting :cookoo:, I understand, but i live in St. Louis, so winter is likely to happen in the next few days and then go away for a week and come back. and i dont run it everyday. i only run it when im checking stuff.
How old is the gas, and when were the carbs last cleaned?
What happened between the last time it ran fine and now?
gas is fine, tank just cleaned, carbs just cleaned within the month. Dont know the last time it started up without already being warm. got it used and not working. Gonna get new plugs so thatll help, cause what i got now are terrible. I think whats gonna make it good will be a rebuild.
