No one here has enough knowledge of two stroke engines to do the kind of modifications you are seeking. A two stroke engine is very simple in construction but very complex in internal operation.
Not so there are lots of us working on extracting more power.
Simply by dismantling the engine, possibly ubgrading the bearings, reassembling the bottom end very carefully ensuring minimum drag.
Then smoothing out any burrs or lips in the induction tract with a Dremel and a fine grindstone.
Finally and most importantly optimising the compression ratio with head shims and selecting the optimum plug heat range for the engine with the engine running at the airborne RPM.
Get it right and the engine will last longer, run cooler and produce more power, a win, win ,win result.
