Wayward Son Posted April 1, 2010 at steady throttle? for best economy or best power? Share this post Link to post Share on other sites
jhondius Posted April 1, 2010 The fact that you ask for the number tells me that you should not be trying to make your own needle. Ask for jetting advice here first. Post your engine mods, altitude and temp. The right needle exists unless you have a really, really exotic setup. Check out eddie's dynographs. Some of them have A/F on them. Flat line is not realistic without EFI. Share this post Link to post Share on other sites
