Derbi GP1 Racing/Revolution - stupid problem

Hi

Recently changed the primary gearing on my Derbi GP1 Racing/Revolution 50cc. The job was real easy,but then i realised something:

HOW DO I PUT IN NEW OIL ???

I allready know these scootrers are the most awful scooters in the universe to work with,but does really Derbi think that you have to remove the engine from the frame,and THEN refill the oil?

Is this a 10 minutes job like on a normal scooter,or a 10 hour job? Are there any tips on how to do this easy ?

 

I solved the problem
