Exclamation 2019 Raptor 90 Mods

I purchased a 2019 raptor 90 for my 10yo son a couple months ago. I'm considering getting him into a race circuit. I would like to know any available horsepower, torque mods that will increase his takeoff and top speed. I installed the Big gun Evo m full exhaust kit and ordered a jet kit from Sigma6. Has anyone tried a different size, model carb on the 90? Any sprocket swaps? Cam swaps? Air intakes? I took the lid off the stock intake to see if it helps. And anyone know of a CDI that will work with it even if it has to be modified? I know you can get only so much power out of a 90cc and I would have got him the next size up if they made another Raptor around 150cc, but the 450cc is way to big for a 10yo IMO. I've searched online and the main mod for the 2019 90cc seems to be the exhaust. Any info on other mods would be greatly appreciated. Thanks!
