TTR 125 Rejetting

Anyone done the Jet & Breather Mods on a TTR 125 yet? If you have, please tell me what Jets you used. I saw a video on youtube and the guy used a 107.5 main and a 17.5 pilot, then reset the pilot screw to 1.5 turns from bottomed out... Bike sounded great, but I'd like to know if anyone else has done this, or something similar, and what you used for jets?

Did it...

Swapped the jets, drilled out the plug and set the fuel screw to ONE turn back from bottomed out..
Fired right up and now, like my 230, it doesnt like the choke. It still takes a while to warm up.. but she's a totally different girl now.
107 Main
17.5 pilot
new gasket

Less than $30..
