A Triumph mechanic, at the dealer, told me after I changed the pipes and rejetted the carbs, that I should consider trimming the intake snorkel. Well it took me about a month or so, but I finally did it. I was reluctant because it is not reversible without buying new parts. WOW! What a difference it made in smoothness and response, through the entire RPM. Range. Triumph mechanic said it would help in the mid range, but it is noticeable coming right off the bottom. I'll admit I only cut it back to just under the divider, but that seems to be enough to get the job done. I think it was running a little rich anyway with the new jets.
