Yamaha Aerox 50cc 2008 electric start problem.

I have a 2008 Yamaha Aerox 50cc scooter and the electric start doesn't work. The starter motor itself is working fine, the battery is good but there seems to be a problem with a gear not engaging properly. I shot a video of the problem so you can see what i am talking about.

Are there any new parts i need to order?

 

The one way clutch isn't engaging properly. Not often you see that problem.

 

Thanks, I'll try cleaning it this weekend and if that doesn't help I'll just buy a new one.
