GZ125 Carbeurettor diaphragm inspection / teardown

[@Techumsa]

I have a Suzuki GZ 125 and I've changed the exhaust to an aftermarket free flow and I added a baffle but the bike started to idle quite erratically,I've looked all over the carb (not removed from the bike) and cannot find any adjustment screws, do you know anything to remedy this problem?

If your carburettor is like the one in the video there are two screws you can use to alter the amount of air flow, or change the idle revs.
The largest screw which you can see with the spring on it, basically changes the lowest position the throttle can stop at, higher position, higher minimum revs and visa versa.
The other smaller screw, I think it controls the flow of air allowed through when the throttle is fully closed. It's much harder to find as it's much smaller.
But you could also be using fuel injection and not have a carburettor at all...
Try and find out what you have, and research how carburettors work. Or ask a mechanic for advice if you can.
I've not worked on bikes for at least 5 years now, so my memory is spotty at best :)
