jd jetting .. please help

Recommended Posts

Ok Ive got a 2005 drz400sm. I cant figure out if i need to use the 150 or 155 main jet and I also have no clue which needle to use{red or blue} or which clip position to start with. I live in the stl area an i ride in mostly warm weather.My bike is all stock except for my exhaust which i cut the one section of baffle out. I also plan to do the 3x3 mod...

I'm not the expert here but if I were doing it.

3x3

blue needle 3rd clip, 25 pilot, and as William already said 155 main. Hope this helps. James

Do the 3x3 mod before a 155MJ, knowing what altitude you'll be riding helps too. I'm at sea level, the BSR 36 had 150 MJ, 25 PJ and Keintech fuel screw at 3 turns. Now running a Keihin CVK40, better than a jetted BSR.
