Removing the shroud is dumb - the cranks perifery is rotating against the reed inflow , so the shroud restriction is there specifically to reduce the interaction between the crank wheels and the incoming charge.
Secondly the machined " duct " opposite the boost port is there to direct a tangential exit flow from the crank' s OD boundary layer , out from under the shrouds trapping action, toward the piston and transfer duct entries.
Thus I believe any attempts at enhancing flow into or outward from the shroud slot is doomed to abject failure.
But hey its a motherfucking twostroke , so everything I have just said could be complete bollocks - and should be treated with the howls of derision it deserves.
Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.
