Wello Pup. lean and rich is how much fuel you are getting. If your bike is stock with just pipe change keep your LOW MID HIGH all in the middle. If they are their leave them. If you have been following around with the bottones re-set and see how the bike runs. to re-set hold down all 3 buttons
Now turn the key on
Now turn the on off (red Button on right) on.
Let go after about 5 seconds
Tap mid button to go up hold to go down. dead center is double line in middle.Do this for each button.

You need to determine what tyoe of map you are running if anythin??

Ninja eater,
Map my busa using is M304-004 for Yoshimura race only duplex exhaust. So please tell me where my low, mid and hiigh range should be for top notch performance.
Does rich means more gas and lean means low gas?
Thanks
