Malaguti F15 Acceleration

Hey, I've got a malaguti f15 02 plate.

My acceleration is poor, I'll be sat at traffic lights then go to pull away and wont move, I have to like run with my ped then it kicks in.

I've tried all kinds of rollers but nothing works.

Would a new Variator and clutch help?

Cheers

 

is it standard, or have you added anything like a sports exhaust for example ??
