Whtrsh Posted December 7, 2004 I'm new to this whole jetting thing and getting ready to install the JD jetting kit this weekend and was wondering what setup you guys run. Should I run the Red_5 #178, or Blue_4 #180? Any help\suggestions would be greatly appreciated. I run a stock '03 CRF450. Thanks! Share this post Link to post Share on other sites
