100% correct. There's a lot of misunderstanding out there about dynos. They are really just a tuning aid. Once you find the settings that your bike makes best power on one dyno it will be the same settings on any dyno. The absolute number is not really important. What matters to me is that when I twist it w/ my buddies ktm 990 I'm not leaving 10-20% of my power on the table

. Furthermore, a bike running at its best settings is running clean and efficient. Google some reading about long term effects on an engine running rich.
Larry, Looks like your bike just had cams, piston, and head work. What did it make before they did the work? If you don't know, than you don't know if you got what you paid for. Also, the dyno sheet says it was 90 deg F at 9:26am? That seems unlikely and affects the dyno correction factor up. I'm not saying FBF did anything wrong, they're a reputable outfit that know how to find hp, but all I'd care about is what did my bike make before and after.
Because I've had my setup for 17 years I have lots of anecdotal evidence on whether my dyno makes good numbers. Brock of "Brocks Performance" has been an acquaintance for years. He got the latest greatest Dynojet dyno 4 yrs ago (I built his dyno room). He knew that the new S1000RR's were making less power on his dyno than everybody else's. Dynojet however will not adjust your software just because you say your dyno reads low. So he came and borrowed my rig and took it to his shop. Whatever the results showed convinced Dynojet to make adjustments and now his dyno gets similar numbers to everyone else around the country.
Another example, my bone stock 09 Klx 250 makes 20 hp. That is a little strong for a stock KLX. So on the same day I had a Kaw making more than I expected and a Husky making less. One forum saying "no way your bike makes that much hp", one saying "no way it makes that little hp". The dyno is just a dumb hunk of metal and wires, it don't know whats up there.
That being said, I still don't get to wrapped up in absolute dyno numbers. Many don't realize it but there are things a dyno owner can do w/ correction factors to make numbers look better, and I can tell you for certain that the guy that just built your new motor/polished your head is never going to hand you a dyno sheet that says he built you a dog... A good friend once took his CBR in for port/polish/head mill job. Bike made less hp afterwards than before, same bike, same dyno. He would never have known w/o the dyno.
