Can anybody assist?

First check to make sure that both of the chokes are not sticking closed after the bike is warmed up. Also check if the throttle grip freeplay is comfortable (2--6 mm) when it sits in idling position. If both are fine then most probably the carburetor may need adjustment & should be left to a trained technician.

My gs500f is back firing through the CARB. the carbs where removed and cleaned they where in good codition.when the suzuki mechanic reassembled the bike and started it the bike dosent want to adjust down...


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.

I had the same problem with my honda. On the throttle body there is a screw that controls idle speed. If your idle speed is around 800-1000 rpm in neutral, tighten the screw a quarter turn each try until the idle speed is around 1500 RPM. Did this stop the idle?
