This is what Andrea Rossi from Sirio says for Break-In

This is the correct Break-In procedure for the Sirio S12 Evo2
1.- One 125CC (1) tank in the bench at WOT with very rich setting of HSN, avoiding it to go on 4 stroke.
COOL DOWN
2.- Three (3) tanks on the track at WOT on the main straight with very rich setting of HSN, as if the engine wants to die, and tuning the HSN at the end of third tank to get almost full power.
COOL DOWN AFTER EVERY TANK
3.- For 20% Nitro, use .20 head shim and N° 7 Glow plug.
After that, the engine will give more power every new tank.
Which means that Breaking-In Sirios, should be done with more or less 300 to 500cc of fuel.

What size prop do you use? I got a wooden 8x6 but from te looks of things the car and air filter will be in the way of the props spinning path.
