Last summer I had the Mi-Val, as rebuilt in RC170-174, on the road and took it to events and shows. It won first prize at the Newby Hall car and bike show, mainly I think because the judge had never seen one before and was impressed by the design for the mid-1950s. A BSA Bantam was close by and the comparison was quite stark. It was difficult to believe they came from the same period, as the Mi-Val looked quite advanced in comparison.
Since rebuilding the Mi-Val, I’ve been gradually improving it. It was a bit reluctant to start, then ran well until warm when it started to misbehave. So I swapped the old Dell’Orto carb for an Indian-made Jetex, which has given a steadier tickover and a small increase in power and pick-up. Stu Thomson, member 2256
