Questions about 03 WR450
Posted January 06, 2009 - 11:27 PM
Have a question about the air box. The snorkel behind the battery has only two passages. Is there a modification for the air box?
The jetting that was in the bike is 48 pilot stock needle OBDUT and in the 4th slot. 168 main jet. 160 is stock.
Came with FMF titanium complete system with quiet core inside muffler.
Also came with some needles. I'm guessing that they are JD because of the color code on the tips. I have one blue and one red. Thanks for any advice.

Dave - Drop the JD Red needle in. 5th notch from top, 45 pilot and 165 main. Fuel screw at 1.5 turns to start with, and fine tune from there. You probably want to do the O-ring mod, too. Or, send the carb off to Zip-Ty for the carb mod - the earlier carbs do well with it - about $100.
Thank you. I'll get on that with the red needle. I'll let you know how it goes.

I don't know if the 03 is the same as the 07 but I took out the snorkle which leaves just one big hole.

If you not doing "grey wire" mod, throttle stop, etc....you prolly don't need to do the cut outs.
