NRG Running Probs

Just Swapped My Rox For A 2000 (v) NRG Extreme... it runs and revs really well when on the stand .. took it up the road and its just compleatly gutless.. anyone had this prob before or can anyone suggest what this could be .. the boy i bought it from said it done it to him and choke was stuck on and to just un-plug it .. but i done this and still no difrent

Many Thanks Ryan

 

If it doesn't feel like its misfiring or running/sounding rough, I would check and replace the rollers. If it is running rough clean out the carb thoroughly

 

Also check your drive belt, make sure it's in good shape and that it's not slipping at all.
