JD Jetting for WR250F

Recommended Posts

Hello,

Can't get the jetting properly even with the JDJetting ? Help please !

WR250F 2004

free mod

Twin air filter

GTY insert

Jd Jetting Blue needle with C-Clip at groove 5

Leak jet at 90 (Stock) Tried the 40 and it was worse, have 70 to try !

Main jet 185

rest all stock

The bike still has a little bog at 1/4 trottle. I need a new jetting setup because I just bought a YZF stock pipe.

What should be my new jetting setup ?

Thanks in advance !

Try-

#40 pilot jet

2 turns out

Red marked needle in #5 from top clip position

#180 main jet

#70 leak jet

Make sure the pump linkage is set to start squirting just after the slide moves upward.

Ride the bike for a few miles before evaluating the jetting, making sure that it is completely hot.

Thanks,

James

Run the YZF needle and jets and you will be very close.
