Would it work to put a weed eater motor on a dirt bike?

[Justice S]

I was wondering if i could put a 25cc weed eater engine on a 125cc dirt bike

You could put on the seat or on your head as it would be as usefull in either position. It just doesn't have enough power and how would you connect it to the back wheel?

It wouldn't be able to move the bike at all.
