malaguti xtm no power

[shuggler]

Please help I have a malaguti xtm 50cc with no power. It will start no problem and idle fine but when try to set off in first on a slight incline it just bogs down and dies! Carb has been off and cleaned.The main jet is 105!
Any one shed any light?

[Nope.]

Did it ever run right?

What colour is the spark plug? It should be coffee coloured. If its oily then your running rich. A 105 mainjet sounds WAY too big for a 50cc. My Sachs 125 is running a 107.5.

If its running rich it could explain the bogging down.

Have you put any 'performance' parts on it?
