Chains are fine.
They're heavier than belts.
For a Duc conversion, it would be possible to make a separate oil-tight case assembly.
It'd be a huge piece for the back of the case, and would have to be made as one piece to maintain oil tightness.
The outer cover would be a problem, as it'd be impossible to remove as a one piece, and difficult to seal if it was a multi piece.

Have to find a set of tensioners and chain guide plates that'd work.
Maybe get lucky finding ones from another motor, that would cool.

I bet you could make one with a two-piece assembly, split vertically, sort of how the belt covers work.  Mount the rear piece onto the head.  Bottom bit would have to be a separate piece too. They work wonders with PVC and composites these days.  Lube could be a small bit off the case with a drip return into the sump.  I am talking off the top of my head.

tensioner would have to be integral to the rear cover piece, so cover would have to have a metal spine.  Plenty of AK47 magazines made like this, with a steel ring spine and composite body -- very tough (dare I say "bulletproof?"). 

Seal would be very critical. 

I would be impressed, but I wouldnt' want to do it...

"Yelling out of cars, turning your speakers out the window to blast your music onto the street, setting off M-80 firecrackers, firing automatic weapons into the airâ€"these are all well and good. But none of them create a merry atmosphere of insouciance and bonhomie quite like a revving motorcycle.

i thought kvar just resold the bulgarian milsurp, but i may be wrong.  my experience is with the bulgarian "waffle" type.  they are pretty hardy.

used to be Tromix would mod them for Valmets.  I have a clutch of 5.56 Valmets and they are superior to the factory Valmet mag.  I think Tony got in trouble with the alphabet boys for modding them, but I can't be sure, he won't do it anymore and won't say why.  I'd get the mags for $20 and send off a dozen or so to him and he'd cut them for $10 each...  >sigh< that's when i could get Wolf 7.62x39 for $60/case from Tapco.

Dems ain't pushrods, those tubes are for the bevel drive for the overhead cams.

yep spinning shafts . wonder how different materials would have made them more efficient and reliable then belts.

That's just a generic bevel drive Ducati. It uses bevel gears to turn the cams rather than belts. Its your "gear" drive.

the material wasn't the issue, it was the complexity of the build.  I forget how many shims are involved in that setup, but it is maddening.  you shim one clearance correctly, then ahve to go back and re-shim the others.  madness, i tell you.  not fun.

good point and Ford is working on electrically operated valves -- no camshaft.
