It has a completely New Cylinder and is fed via a cast reed block welded to the crank case incorporating an RB reed. The crankcase throat also has a cast block welded in to take the Third Transfer Port. The Prototype has been running around the country side for a few weeks. The price has not been 100% set as yet but the first 4 ordered will be finished by the end of November. Power spread is brilliant.
Reed Block might well be sold separately as a DIY kit, Prices will be made available in a couple of weeks.
You can see a video on my Face Book page of the engine running. RM......Now added here too
