im dang close on tuneing but kinda hit the wall as to where to go.
currently
160 mains, main needle raised to #4 slot, 17.5 pilot, 39 grams in the clutch, tightened secondary to middle hole.
getting 900 degrees and 8000 rpm wot
off the line from a dead stop it take off fairly smooth, and roll on power above 1/4 throttle is sharp.
its that 1/8-1/4 rang that falls on its face?
maby I should go back up one pilot size and play with the air screw more, I already did that but didn't change the needle. possibly it could make a difference?
