Talk to Mick Abbey - Portgrinder, he is here from time to time and can help you in what ever capacity you need.
A great deal of restriction to performance within the RD engine is in the transfer port base where the cylinder wall masks off about 40% of the flow from the crank case into the transfer port itself.
Also, the exhaust port can be altered to suit but you would want to consider the entire package - pipes, carbs and ignition as well as the combustion chamber volume and squish clearance - leading on to fuel suitability.
Give Mick a call - v helpful
