Even then, aside from some AWESOMELY raunchy noise under full throttle, the bike makes no more power. I did notice a loss of power taking off from a stop, but it was negligable. As Badbob mentioned in another post, it was, unfortunately a waste of time.
I'll post some photos from the process tomorrow morning.
I'm a bit discouraged, but I've got the bike back together and she's ready for the ride down to Franklin tomorrow.
SEe you then,

Which filter are you using right now? I bought a small one and the jetting is similar to yours, but without filter even a 130 is still lean at full throttle.
Now I'm waiting for a big K&N filter and I spect a higher jetting than 125... Keep in mind that a "richer" jet needle could increase power too (the stock needle limits the maximum fuel flow of bigger main jets, even shiming it) and a bigger pilot jet will remove the power loss at taking off, as I've checked.
Also, now it's possible that the exhaust system would be the limiting factor.
