Does the 04 450 need the BK Mod?

5 posts in this topic

I don't believe the WR450's (2003 OR 2004) needs the bk mod done. I haven't done mine on my '03 and it runs great. I did have to do it to my '02, though.

03-04 don't need the BK (sorry to repeat that). There is a screw to adjust the squirt. Look in your owner's manual. And I did have to change the leak jet to a #40 for best results.
