Hi all, my speedfight 2 ( 50cc) has sudenly started to bog when u go from quarter throttle to full, it will just die for a second or more then pick up again, its running very boggy !! Iv tried adjusting the mixture screw but still no change ?? Also, its using a hell of a lot of petrol recently, this as all started happening out of the blue ! Iv cleaned the air filter and checked the spark plug, all good. Any ideas ? Cheers !
id say wait for a bit.. (day wise) or let the bike warm completely up (leave it like on idle for at least 5 mins) and see if it carrys on. reason being because i had a similar problem today (it would die then pick up again) but thats because the weather was crazy.
