Hi George, in the late 70's my brother had a Land Rover with that style engine. At 90mph, the 'aerodynamics worse than a house brick' meant the door tops got sucked out about an inch. You could also watch the fuel gauge dropping like the second hand of a watch! Video also missed out on Ducati with desmodromic valve operation (I don't think anyone else uses it?) The head shown around 7 minutes looks like a Triumph Dolomite, direct operation bucket one side and rocker for the other?

@BruceDragon-sf1tr Honda have been using wet belt in industrial (fixed rpm) engines for almost 30 years. It's probably why they thought it would work in automotive?

@The_R-n-I_Guy Yep, Ducati bevel gear OHC

I'm very familiar with the V-4 Honda motorcycle's and hate them with a passion. I don't care how good they became in later years, the early ones were complete shite with numerous problems. Even the gear drive VF750 wore out cam gear 'cartridge' really fast (never mind the bikes where Honda 'forgot' to harden the cams) I started at a Honda dealer workshop in late 1970's, moved to a Suzuki dealers 1980 and worked on V-4 Honda's at least once a week for several years. Moved to America 1999 and still worked on junk V-4 Honda's (mainly V45 Magna) Seems I always get the worst designed motorcycle engines at dealers (doubt anyone else understands them?) Kawasaki used silent chain so lightweight it was completely worn out in less than 20,000 miles (600cc and 750cc) and if not changed would break before 30,000miles. Honda wt belt in industrial engines isn't rubber, the one I looked at was bright blue 'plastic' of some kind. Solenoid valve operation requires a high amperage for high rpm applications. I know there have been developments in the last 20 years (you used to be able to go directly to development website, around 2005~6) Apart from that, this was a very good engine primer for camshaft drive types
