What is the suggested needle settings on a the tuned motor, and what comes from the box?

i measured mine last night for another thread ...from the factory my needles were

hsn 3-1/2 turns out from bottom

lsn 6-1/4 turns out from bottom

originally thought i would have to lean it a bunch to get it started ...put only 1-1/2 turns in form factory on the lsn ...and 1/2 turn in from factory on the hsn ....fired right up ...didnt turn the needles a bunch after that ...just for break in ....

You can always take the head off and see what shims are in there. If there are 2 you can take 1 out. If they are different thicknesses I think you take the thicker one, not sure though.
