Roadholder 370 - October 2018

10 $30.00 has also changed. The inside has all the same plumbing connections as a standard Dominator timing cover but the oil pump position is not the same. The crankshaft is clearly a Model 7 clone (it has a 72.6mm stroke) as are the conrods (Model 7 again, only slimmer versions). The engine follows Triumph (and Navigator) practice in having two camshafts ahead and behind the cylinders rather than the 'standard' Norton Big Twin practice of a single camshaft ahead of the barrel. The crankcase mouth has been widened to accept a Triumph 500T barrel bored out to use 65.5mm sized pistons. The Model 7 uses 66mm size pistons as standard, but the original Model 7 pistons were actually war-surplus 65.5 + 0.0020" items liberated from the German BMW factory and given to the Bristol Motor Company in huge numbers, who then sold a good number to the Norton factory. A flat platform behind the barrel assembly was intended for the fitting of a magdyno. I have attached a couple of photos of the engine I am intending to use in the frame. This is believed to be prototype engine number three and is the one that contains the very obvious Model 7 look-alike parts. However, there is no way, at present, that this motor can definitely be confirmed as one of the Moore prototypes. If I can get hold of these missing parts, from engine number three or manufacture replicas then I can restore Moore engine number two back to its original state, which was totally complete and ready to run but was robbed of many parts in order to get engine number three in a frame and working. The trouble is it needed to be mounted in a chassis similar to that of a 'Trusty Tractor'. The timing side as-is What might have been with upright gearbox and plunger suspension ... The crankcases as 'might be'
