I'm not performance tuner, but I'd say it's really hard to say tirekiller... power is a very subjective thing unless you have dyno numbers before/after or something like that. If you are going by feel, it's a lot harder to really know what is going on. But, for some suggestions, I would do a little more baseline diagnosis
1. a compression test, or better, a leak-down test. See where your cylinder compression is really at
2. air/fuel reading w/ a dyno run and a carb inspection. If your carbs are off you could be losing a lot of performance. I know it doesn't seem likely that the carbs go from good, to all of a sudden a problem, but it is possible - jets clogged, diaphram punctured, who knows.
3. Did you make any changes along the way, any chance something robbed you of performance?
Where do you think you are down on performance? Low end grunt? mid-range? Top-end? Equally everywhere?
