Need Help Jetting for my Drz400s

Recommended Posts

I bought a two brothers exhaust and JD jet kit for my 2006 Drz400s. I'm at about 800 feet elevation. I put the 160 main jet in and the 25 pilot jet in and the exhaust on and the red needle with clip 3rd from the top and the 3x3 mod. Fuel screw out 2.5 turns took it for a ride. Went to check the plug it was white. Tried again at 3 turns... still lean. Any suggestions??

Maybe try blue needle 4th clip if you have full uncorked exhaust. What do the jd jet kit instructions call for.

Plug doesnt necessarily mean anything. How do it run?

It pops pretty good on deceleration but otherwise runs good but definitely runs lean. I used red needle before cause it said to if it was 75+ degrees and humid which it is normally.

 with 3x3 mod, open pipe @less than 3000ft , use...

 

 

160 main jet

Blue needle, clip 4

22.5 pilot jet with extended fuel screw or 25 pilot jet with stock fuel screw

2.75 turns

 

You should be getting some popping on decel if the pilot circuit is tuned correctly
