does anyone know why my Yamaha 50cc scooter keeps cutting out on me? will it be anything to do with putting a new barrel in then putting a new piston in that was bought separate! it cut out 3 times today in 30 min

if it has a new barrel and piston then you should be running it in ,you should be on no more then half throttle and only doing small trips and extensive riding or high speed riding will cause a seizure and damage the barrel and/or piston.If this is the case then i expect you have seized it several times already.
