I got a conversion kit in order to change a MV 350 OHV pushrod engine to a DOHC 4 valve one. It was made by Ioannoni and only two of the are installed in Ipotesi bikes. Now thes are driven on the track. I got these kit including the costruction plans and cast models. But without the cams and drive spur gears. But i hope, I can complete an engine with this parts. It would be an 350 two cilynder what I always dreamed of.
