Well you have the high compression setup. If you want more pulling power I'd lengthen the intake a bit, remove the baffle from the exhaust (if using the standard chinese 2 stroke one) and open it very slightly using a step bit.

and by slightly, I'd make it just 4-5mm larger than it's current opening diameter

Shorter intake and more open exhaust is higher rpm but less pulling power and vise versa.

The intake expansion chambers (boost bottles) have felt like snake oil to me. I haven't seen any improvement from them, just a change in sound that some perceive to be an improvement.

If you're feeling brave you can run nitro to the intake. I will say it is fun, as long as you don't have to turn and there are no potholes.

They do work, but only for a short stent and it's risky
