Awesome thread! I just did the jetting, airbox and exhaust mods to my girlfriends 05 TTR125 and it made a big difference. The stock settings were horrible, the bike wouldn't run off choke or rev but now....WOW! I actually think it will be easier for her to ride because she won't have to constantly mess with the throtttle to get it to rev without stalling. She loves the way it sounds now too, not so whimpy. Thanks Ovrrdrive, you rock!
