hi i been looking to upgrading my daughter's 2 stoke and i was wondering what high performance parts work the best for it .

 

The best upgrade for the money will be in your clutches. I would try experimenting with different weights of rollers for an easy, inexpensive gain. I believe the engine is a JOG platform, which means you can use some of the 2 stroke 50cc scooter performance parts with the same effect.

If cost is less of a concern, there is no subsitute for displacement. But, when adding a big bore kit, little gain will be seen without spending a fair amount on upgrading other components on the engine as well.
