hi all I picked up my demonx 125cc last week but have a few running issues. when I got the bike it would start straight away but had to hold it on throttle til it warmed up. so I decided to tweak the mixture screw now it banging and popping a treat! im not sure what to do?

You've gone too lean on the screw, go the other way to richen it up and stop the popping.


It's like a willy. Leave it alone unless you know what your doing with it.

Lol . Seriously how many adjustment screws is there?

[Dangle_kt]

1 mixture adjustment screw, 1 idle adjustment screw.

The idle is the top that sits at 90 degrees to the slide tube, on the side of the carb.

usually the mixture screw is at a funny angle - like 45 degrees to the carb, and has a flush srew to stop accidental adjustment.

Try screwing it all the way in (gently) then turn it 1.5 turns out.

That will be a reasonable start point. But as katoom said, its no where near as simple as turning a screw to get it set up spot on - so try to leave it along once its running ok.
