i just recieved my cy29cc from ddm today,iv installed it and broke it in,now my question is how do i set the tune

my hs is 1 1/2 turns out


my ls is 1 1/8 turns out


i have not messed with the ls,the hs i have messed with a little,i just wanna make sure im not running it to lean.
 
Your plug will tell you where your tune is at. Do a high speed run, kill it quickly and pull the plug. If it's a gray/ash color and dry, it's lean. If it's dark and wet, it's rich. What you want is something right in the middle, like a brown paper bag color. When you're tuning, go 1/16 of a turn at a time and check the plug often to gauge your progress.
 
Don't forget, too, break in can last up through several tanks although you can get into it more after the first couple. By the fifth tank or so, it will really wake up and that's when I would tune for performance.

Good tips by Deluge btw.
