7 forum posts | The cover of MEW 144 with a very nice pic of the Manx engine got my attention, because I have been searching for the drawings and castings so I can construct one myself.
Maybe the maker of this Manx model , B. Conner, can hopefully help me to get the relevant information. |

I'm not sure if he uses works drawings or has access to the original engines to measure. He usually has at least one engine running at the Guildford rallys.

310 forum posts 1 photos | In the 10 November 1955 issue of the Model Engineer (sorry but I do not know the issue number) there is the first of a series of articles on modelling a Manx Norton by H W Hooper who 'gives detailed instructions for making a scale model of one of the world's most famous racing motorcycles' in 1/6th scale. This engine/gearbox are non working parts. Jim |

80mm bore x 100mm stroke gives approx 500cc
1/5th scale = 16mm bore x 20mm stroke gives approx 4cc
3/5th scale = 48mm bore x 60mm stroke gives approx 108cc
I think that most of his models are half full size which would give 62..8cc
