Rotax dont have a graph for a motor that’s on the old rod/crank/piston with the newer upgrades.
My guess is that an 09 spec with upgrades would be on par with a “full” evo. The difference you see in the curves is mostly down to ignition, a little carb and a little powervalve.

Maxspeed (gorotax.com) and their distributors will be stocking the kits starting in Janurary.
