I get a really bad flat spot and its all the time I can't rev to far, I got 52 not sure if it's de-restricted or not. second hand, standard exuahst.

There is damage to the exuahst but not sure.

The spark plug could very well be something to do with it. It doesn't cost much - you may as well change it, as the condition of the plug is very important on small 2-strokes.

What exactly do you mean by a 'flat spot'? If it's your first scooter, are you sure you're not just used to having gears? A scooter is meant to rev up to a certain RPM and then stay at that RPM whilst the speed increases - it's the way the transmission works.

If you got an indicated 52 out of it (which, by the way, willl probably be more like 40 at the most - speedo's lie) then I'd say there was nothing at all wrong with it.

I coulnd't get it out me and my mate tried with the tool but it was soooo hard to get out we couldnt!

if you get 52 on a "moped", my guess is that it is de-restricted. lol.

and fix that exhaust. I had a dint in my oil manifold, led to my piston going and then piston rings in the exhaust ruining my exhaust too. dints in the tank, exhaust or other places aren't good. lol

It was more than lightly the spark plug not the jet mate.

No cause I did the spark and it was still being a cunt, so I put 60 jet in when it had a 56 jet in it and it was fine, and now my ped rinses mate.

after a few miles, take the plug out and check the electrodes are a nice light brown colour, this will let you know all is well.
