February 7, 201115 yr hi, a friend of mine has recently bought a scorpa sy250 2001 model but it doesn't start and when it finally does it runs rough! What am wanting to know is; The correct fuel air mixture on the carb? how many turns out should the mixture screw have? what spark plug is required for this year bike? What gearbox oil should be in the bike and how much needs to go into it? the clutch is also sticking on this bike but the bike has been stood a year, new fuel has been put into the bike but not the gearbox oil, is this the cause of the sticking clutch? also any other information about the bike to make it run smoothly etc etc would be much appreciated. Cheers!! Edited February 7, 201115 yr by coxy_gg
