ttr125 jetting

[sparky yzf]

I need some jetting advice. I have a ttr 125 added a pipe ,did the airbox mod and went to the 112.5 main jet . When the bike is idling and I wick the throttle it dies , is it to lean or to rich . The needle clip is in the center position should I move it up or down? this is giving me fits since I am a novice tuner. any input would be most helpful in solving the problem

No matter how it's jetted, "wicking" the throttle on this bike (from idle, I'm assuming you mean just sitting there in neutral, not riding) will cause it to die. Your jetting sounds ballpark, if it's running okay on the track I wouldn't worry about it.

Try to stay away from "garage tuning." Jet your bike by how it feels riding and taking plug readings.

If you're still not sure of your jetting, do a search for TT-R jetting and you'll find many helpful posts.

Good luck.
