David,
Thanks for the comments. Actually, figuring out this air cleaner
issue is just the latest and about last thing necessary to doing
really clean installations of the larger Triumph engines. The
elements involved include:
A stronger clutch system
Carb and intake manifold
air cleaner adapter and retainer bracket
exhaust manifold and J pipe
engine front plate for the larger engines
fan and water pump parts (as necessary)
throttle linkage conversion parts
I already sell the high performance clutch system and if there is
enough interest, I would be willing to package the entire system. I
would expect it would cost about $1500 -$1800 for the whole works.

If you want to see some more pictures, there are more at the same URL
listed below. Simply change the number in your browser from 01 - 23
to see them. Most are about the same shot at different sizes and
lighting but the first few show the carb with adapter and retainer
bracket.
