Proper jetting is a real "seat of the pants" thing. Just like engine noises can't be diagnosed to the "T" over the internet, nor can jetting. You can get a round-about, but like already mentioned, nobody wants to be responsible if you sieze your bike either. It also helps if you provide your general elevation where you ride, all mods are listed including what fuel, octane and oil mixture is used.
I have an '07 with Gnarly Pipe, Q-Silencer, Stock Reed Cage w/ Boyesen Pro reeds; jetted for sea level and 110 Leaded Race Gas mixed 36.1 w/ "Super M." It's been so long since I jetted that bike (don't remember exactly whats in it anymore), but I had to lean the jetting out alot to compensate for the race gas light specific gravity (much lighter, flows way better then any pump, especially the E10 around here). (believe Pilots @ 42, next step leaner needle @ 2nd position, Main I think is at 155) ...BUT, I can only use Cam2 110 leaded at this lean jetting, pump gas would turn it into a paperweight.
Like Kevin said, with jetting, there is no "one size fits all" application. One change at a time, read some articles on the jetting circuits and what part of the throttle range the affect prior to tinkering. Also, it helps when new to jetting to mark the throttle positions on the inside of grip flange (closed, 1/4, 1/2, 3/4 and full throttle), mark on the throttle housing boot the closed position. That will give you an at glance look at which position in the throttle/rpm range is the issue (airscrew & pilot - upto 1/4, 1/4-3/4 needle, 3/4-WOT main; there's overlap as well between circuits, but this gives you the general idea to help pinpoint which circuit where you feel the bike either blubbering, breaking-up, falling flat, etc.). Always jet with and use the same fuel grade as jetted for, have a clean air filter, fresh packed silencer, mechanically sound (goes without saying) & fresh plug. Good luck!
