Pete, I know this is an old post... But on the off chance you never did the cam swap bob suggested, and you still wish to do so let me know... As I have a 450 Scrambler camshaft, and we would both benefit from swapping camshafts. Also one question on your Carb. I don't know very many details on the mototrans motorcycles, but I did come across an Amal Concentric 930/68 Carb. in my dad's stash of duke parts that my brother and I have been sorting through, so as to catalog and acquire the needed parts to restore his 350 mark III desmo. I had assumed this carb. came from an Ossa, because we also found triple trees, forks, wheels from an Ossa (we believe) along side the carb in question. The Ossa was spanish too and from what I understand Amal had/has ? a factory in spain, and the majority of motorcycles built in spain back then where fitted with Amal carbs. So my question is, do you know what model your amal is, because it looks identical to the one I have here, also note if you know, does it have a steel lock ring that threads on to the o.d. of the inlet ( where a velocity stack, or air cleaner elbow would thread onto a dellorto equipped duke) I noticed this on mine, and had assumed someone used this as some kind of adapter but it may be that this is a factory mototrans carb, and that the ring I speak of is actually used as something to secure the air cleaner too. Any info would be appreciated... Bob may know this also if he still has his mototrans...
