Welcome to the forum, champ. It's a little quiet these days. Your bike is commonly known as a Cat Eye.
There's not many go fast bits for those particular style of pocket bike available anymore. You could try some american websites like Pocket Bike Performance Parts but they are a little expensive.
I personally don't know anything about your particular style of bike but hopefully one of the more knowledgable types might fill you in more.
Good luck, son.

I had my first ride on it today as I have been doing repairs. It doesn't rev to 10000 it shuts down at 3 quarter throttle (oh boy new clutch). Could you suggest any brands for parts.
