You stated that you "left it alone for a while"....if that is longer than a year, theres a few things that can happen here. Sounds like your pilot jets (idle jets) are plugged up and your float is sticking open. You should probably clean the carbs quick and see if that helps.

Otherwise another problem could just be that your Idle adjustment is set wrong. There should be a knob off to one side of the carb towards the bottom, usually has a black plastic or white plastic knob thing molded to it so you can change the idle by hand. But again, I'm pretty sure its your pilot jets plugged up.

I'll attach a picture of a carb for you to help. This is NOT your carb it is actually off a 1974 TX500, and the configuration is a little off, but it should help you a little bit. The pilot on yours is going to be about where I circled it in the picture (on this picture the pilot is actually under the black thing between the two I circled) but this should still help. The smaller one will most likely be plugged up. Goodluck!

2003 Suszuki DRZ difficult to start.

Make sure you are using the choke - which is actually not a choke, but a fuel enrichment circuit in the carburetor. The lever is located down on the carburetor. Also, you can try draining the fuel from the carburetor float bowl. Sometimes, just enough water will collect in there to make it difficult to start when cold.

Removing the carburator on a suzuki drz, 125.

It is quiet easy, you remove the seat then the fuel tank this will expose the carburetor then its simply a matter of disconecting fuel line and unscrewing attachement screws. why do you need to do this? I would be very careful doing this as any dirt or dust or grime getting in can have huge impact

Carb problem

You have an air leak that is making the fuel mix too lean. Probably intake manifold gaskets. Other sources are reed valves chipped, deformed or broken, cylinder head gasket not fully sealing and crank seals gone bad. Your bike is 20 years old, I don't remember if your bike has reed valves.

The dealer is not going to have new parts. google " suzuki motorcycle parts " and " antique suzuki motorcycle parts "
also google " motorcycle salvage suzuki ". This should give you some sources for parts.

Please rate this solution. Thanks weldin_fool!
