The crankshaft would be the real problem ,you could likely adapt the cylinder to reverse the intake and exhaust as many small engines use the same sized valve for intake and exhaust .Would be a fun project .

Would that be from an odd firing twin?

Re: The Saito twin that never was

The 30 used a single cam with only 2 lobes that were shared by both sides, this is the same setup I used when I did my home build 106cc 4 cycle . . But you are correct the saito twins that used separate cams had a L&R side cam .Much easier to make the single cam setup because you can make your own cam .

For odd firing you just time it different but that depends on what crank you have .The odd lobe spacing on the left cam is because they reversed what lifter opens first , this requires you add the spacing difference between the lifters to the cam lobe spacing .
