My RP has a rubber mounted low frame crankcase (n° 238100 so 1935) and the only issue is the bulkhead to flywheel cover interface. There are no issues regarding the starter shaft/rad position. At some time prior to my ownership someone had " modified" the bulkhead to allow the engine to fit, raising the aperture a little to allow the slightly higher engine position to pass. Subsequent engine remova/replacement requires removal of the flywheel cover but apart from that everything goes in and out OK. (I don't even have to remove the throttle shaft). There are no mods to body mountings, cow horns etc., and it's been like this since time mint imperial with no issues whatsoever. Standard rubber mounts used.
