So i bought a 1985 Suzuki Madura, and it's all there... have already checked comprcompression and fire and it's all good. All I was told I needed was a new carb kit, so I bought the carb kit and would love a little help on how to install them!?

SOURCE: my '86 suzuki savage won't rev up it just back fires

When I had my savage it backfired all the time. They are known for this. Make sure you fuel is not to lean. Just adjust the fuel. You should adjust that and put some sea foam in it or ethenol treatment since most of the gas is terrible these days. Running 91 octane will help. Also you will want to replace the muffler gasket too.
When you replace that it will smoke which is normal.
I sold mine but I know the bike pretty well from tearing it apart due to trying to fix it from not running properly. Let me know if you have any more issues.

SOURCE: i bought a brand new 2007 suzuki swift,it has only.2007 SWIFT

i would say its wear and tear,you can kill a clutch in a day if your hard on it,,,or it could take 150,000 miles,,suzuki will classify that as a wear and tear item,,they are really tight with that stuff,

SOURCE: suzuki gn125 wont start. checked carb, cdi, coil.

Check the valve adjustment. If a valve is standing open just a little, the compression will be too low to start the engine. Check fuel delivery by dribbling a little gasoline into the carb and try starting the bike. If it starts and runs for a second or two, you're not getting fuel into the cylinders. Check you carb again.

Call a Kodak shop and ask what causes that problem and how to eliminate it. It's probably a setting you need to change.

SOURCE: my gs500f is back firing through the CARB. the

Lean mixtures burn very slowly, at times slowly enough to continue burning through the power and exhaust stroke, causing a backfire when the intake valve opens, and that flame gets a shot at the new mixture charge.

In normal operation, as the engine slows, the fuel delivery from the main circuit falls off, and the idle circuit is supposed to take over. If the idle circuit flows insufficiently, that becomes a transition to fuel starvation.

You can try pointing an unlit propane torch into the inlet air, and see if you can get closer to an idle while supplying a supplementary fuel source. You will need to do this in a way that gets propane to both carburetor inlets, maybe rigging a Y with vacuum hoses and electrical tape...

This started with work on the carburetors, so the fuel system would be the most suspect. That, and the fact that it will run at higher RPM would seem to rule out fuel delivery.

I was looking around at photos while developing this answer (needed to know whether this was a twin or a 4-cylinder), and one resource said the idle speed should be 1,200. I don't know if that's right, but maybe 1,000 RPM is too slow for this motor to keep it together. (I do doubt that, though.)

When I wrote that last sentence, I started to second guess myself, thinking "What if the fuel shutoff(s) is/are vacuum operated, and as the bike approaches idle there is insufficient vacuum to hold it/them open?" But the I rejected that, because there is even less vacuum at cranking speeds, yet the bike starts.
