Howdy fellas, first of all Happy Easter.
This morning i took my bike for the first true ride since i got it in december and i put it back together; since then i made just a few very short ride around the neigbourhood and all seemed fine.
I have to say that i've checked the forum for this problem but seems that i found nothing that fits my condition so i decided to post my question; if there's already a tread about this i apologise in advance.
Here's the deal: the bike starts fine, just a bit of black smoke at idle, but i thought it was because the bike it's a '94 and at that time there was no unleaded fuel here, and also the muffler it's the original one so i thought it might be part of the reason of the black smoke.
So i took it for a spin and as soon it got warm it started to run clumsy, and when i stopped at traffic lights it seemed it want to die...i was able to get back home and it died definitely, and it didn't won't start again.
I waited it to cool down and it seems to try to start but it doesn't.
Here's what i've done to it: new air filter and new oil filter (originals) new spark plug, new oil and Raptor petcock.
Seems to me that as long as the engine it's cold it runs good, but as soon as it gets in temperature the trouble starts.
To pass the emission test the dealer had to re-jet it but as soon as it got the stamp they put back the original jet.
Any suggestion it's highly appreciated.

Hi Dave, i really don't know... but your hint it's a start, i will check the carb and let you know asap...
In the meantime thanks a lot

had the same problem with my 99. didn't have any black smoke but it ran clumsy and wanted to die ALOT. so I pulled apart the carb and did the small rebuild kit, cleaned the whole thing up, ( the small kit is a new needle valve and seals. think you might want to change that jet to a new one.) the bike has not ran this great since I bought it. and I can tell you now that the po didn't know what he was doing when he did repairs. hope that bit of info helps.
the only problem I had when I did the rebuild kit: a lot of the screws on the carb had been stripped out. had to remove and replace most of them.

Thank you all guys, as always you're the best I have just one doubt: i have little to no experience on dealing with carburetor, so do you think this work can be done by a newbie like me or do you think it's best to take it to the Suzuki dealer and let them do the job?
I have the service manual, but it scares me a bit to do this thing, but at the same time i would like to learn... is it too much too soon?
Thanks again to all of you

He's in Italy Dave.

Max, it's very easy. 2 hose clamps and 4 screws. Carb or brake cleaner aerosol with spray tube. Small Philips and small flathead screwdrivers.

Check the tech section of the board for the real recommended method of cleaning.

My way: Drain float bowl. Loosen the bands on the rubber pieces the carb rides in, rotate carb top to the bike's left. Remove the 4 bowl screws, pull float bowl off. Remove float. Remove the round brass flat head screw looking deals with a hole in the center (the jets). Run a sewing needle through them, followed by spraying cleaner through them. The needle will just push any lodged gunk out.

Reassemble in reverse order. Replace float bowl retainer screws with stainless steel allen head screws.

Add Seafoam or similar outboard engine fuel system cleaner to the fuel, set petcock so it will fill the carb, start bike. Ride.

WD.  I just did a seach.....Seafoam is not available outside the US.

I read the symptoms and told him how to start it.

Drain the bowl into a clear jar.

Drain some fuel from the tank into a clear jar.

REport results.
Also, note how the fuel flows when draining from the tank.
