Also, lean out your HSN 1/8 turn.
An 1/8 turn is half of 1/4 turn. Imagine looking at a pizza. Now imagine cuttting it into 4 equal pieces. OK now cut those 4 pieces in half. You should have 8 pieces, each of them being 1/8 of the pizza. Apply this to your needles.
I would start by ignoring my first post, and just begin with leaning the HSN 1/8 turn and see how that is. If it's still not reaching top RPM, lean it out another 1/8 turn.
Do that untill you get your top-end down. If when you get your top-end adjusted right and your off-the-line accelleration isn't what it should be, adjust that, but before you mess with the LSN fix your top-end.
LSN adjustments:
-If when you accellerate your engine bogs down, lean it out in 1/8 turn increments.
-If you you accellerate the engine revs up quickly and dies, richen it up 1/8 turn increments.
Just play with your needs a little bit, but only do one needle at a time. Also, don't mess with your MSN, you most likely don't need to. Keep at it man, you'll get it down!
