I think the conventional wisdom is that the side draught is a better
performer but is worse on economy. I have not seen any direct comparison
to back this up however.

Yes, I don't think you'll have any problem. You may have to rework the
linkage but with the cable linkage, it shouldn't be too much of a
problem. I have a friend who put on the down draught and he has a gone
through a couple of accelerator cables because the linkage kit that came
with the carb made the cable come in at a funny angle. This caused the
cable to rub against the cable guide.

I would recommend the TriumphTune performance catalog to any Triumph
owner thinking about making performance mods. They have a section
devoted to each model Triumph made. They have a "systems" approach to
their modifications which I like, and have many components that they have
designed and built in house. They have a 4-2-1 header and twin exhaust
system that I am drooling over! They charge for the catalog but it is
money well spent in my opinion as it is very well done.
Good luck,
