No, I did not advise anyone to install a PC, this is what I stated:
"Most suggest that if you remove them, you add a Power Commander PC V or similar to re- map the fuel mixture. That said, there are people out there who are running the bike with the 'flies removed but otherwise stock and have reported no problem doing that either. "
Note the words 'most' and 'suggest', I did not advise anyone to do anything, I merely mentioned what some suggest. It is not my place to tell others what to do / not do with their property and I do not do that.
As to what I have learned from this thread, I have to say that I cannot think of anything. I think I have a very good understanding of how IC engines work, including the control schemes used on modern vehicles including the C-14. And I believe I understand this from several different angles including the chemistry, physics and mechanics (for example, I understand why the Wankel design, though fascinating, is a lousy design). But as I said before, I am no expert, merely a student of those with so very much intelligence and talent that have preceded me and did me the courtesy of writing down so much valuable information. I do not believe I would have surmised Bernoulli's principle but I am able to grasp the concept as long as I read slowly and carefully enough so as not to misconstrue what Mr. Bernoulli was trying to convey.
And mentioning your valuable information just reaffirms that you really think a lot of yourself and your knowledge. Too bad because if you were to look at just a little bit of the world, present and past, you might realize that there are, and have been in the past, some very intelligent, able people, far beyond average and into the 'gifted' range. I know this because I have followed some of those people's work but I do not remember any of them having to point out how valuable their writings were.

as far as the OP's question about removing flies, the advise you gave was to install a pcv. If the OP (and you too, Brian) Haven't learned any valuable info in this post and my last post, then I really have to wonder if anyone really wants their bike to run better, or just bolt on stuff so they can say "I have this on my bike, so it's fast".
