I’ve seen three bikes now with V-Twin engines made from radial aircraft engine cylinders and heads. Some very clever people have produced their own crankcases and crankshafts, camshafts and suchlike to create an engine. Two of those were in Australia and I didn’t get any photos. One was a race bike and the other made into a ‘servicar’ (hybrid trike / outfit). The third is the Flying Millyard. A quick google will tell you all about that.
I did wonder about doing that as a project, but the trouble is – it’s been done! For the amount of work, hassle, expense and general effort it’s not worth it (in my mind anyway), to be just ‘another one’.
A while ago I was talking to the guys in the Enfield owners club and they jokingly suggested I made a single cylinder bike engine. That would be something like a 2.5 litre single cylinder bike! Actually I really like that idea. I’ve always had a big single chopper in my mind, or flat track racer. Food for thought anyway…..
