I bought I ped last week now it won't start?

Last week I bought a Honda sky 50! It has been looked after well and is in good nick! It started using both the starter motor and kick start! I went to get it out of my garage today 8 days after and it would not start! The battery was fully charged and the starter motor did turn! There was plenty of fuel and the spark plug is okay! Any ideas why it won't start?

Hi so take it to a motor cycle dealer for some servicing and repairs.
