I have changed my timing to YZ spec. tried the Baja Design jet kit and it did not work (too rich). I am back to the stock jetting (165 main, 45 pilot and stock needle on 4th clip). Air box lid and the exhaust insert removed. Air screw at 1 ¼ out.

Bike starts on first kick and idles good. After warm-up if I twist the throttle open very fast there is a momentary bog. If I open it slowly then no problem.
When I am riding, there is a spot between approximately ¼ to ½ throttle open, I hear a jingle sound. It sound like there is loose screw or a metal piece somewhere in or around the motor. The sound is not there at idle or ½ to full open throttle. Is this pinging sound??
I have not checked the plug yet.

Hi Rocky,
I'm somewhat new to this WR/YZF stuff but it sounds to me as your too lean at the bottom. I was writeing to ask you about the Baja kit, is it worth it? and what's in it?

the baja kit consists of:
Instructions to change timing to YZ
YZ throttle stop screw
48 pilot
172 main
OBDV R needle
it is around $25. since i am not running an aftermarket pipe, the BJ jetting is way too rich.
