Rob, I'm sure you'll hear from others on this site that the factory Triumphs are set up VERY lean (ie: too lean). Even though Triumph may say that you "could" use the stock carb set up, it almost certainly would not be the best. I had my bike for less than 2 weeks before changing pipes and jets. The headers were already blueing from running lean. After the new pipes and main jets, I had to change the pilots due to excessive popping on decel. I ended up with exactly what came with my exhausts and what they recommended. It has run incredibly well ever since and there has been NO blueing for 2000 miles. I owned a Bonnie in '71 and I can't believe how reliable they are now. Once you get it set up right, you shouldn't have any problems or spend time "wrenching" (other than chain adjustments, etc.).
