wr 400 accelerator pump time, jd needle question

1 post in this topic

today i was playing with timing the accelerator pump. I installed the thin oring with the jd jetting kit and i also have the Bk mod.

I used a video camera at 15 fps, and I timed the squirt to around 13-14 frames..... or a little less than 1 second. Does this sound ok?

my bike has all the free mods and yz timing, so should i use the jd jetting instructions and use the blue needle at the 4th clip down? thanks

oh, im at sea level
