Yea, why didn't corporate Triumph offer or do this? They had the precedent one carb model, historically. Oh wait, they gave the Tiger name to another type of bike. I'm not sure that a bigger carb is needed as only one side hits at a time. I could be wrong about that, though. I wanted to try this since the first day I looked over the fuel arrangement. Back in the 70 s I had a 70 TR6R and a 76 TR7RV..Tigers, even factory racers had one carb, The TR6C. It's the damn 270 timing thing, that made me unsure as to not try and tig weld one up. I have a good condition sidedraft carb (SU) from a TR-4 sports car, I think that would work just dandy, not to mention would polish up and look cool.
