Race tune is around 2 1/4 out on the hsn, half a turn in from flush on the lsn. Lsn is horizontal also, this also depend on where you race too. But this should get you close.

Sandy, Whats up!

this is good starting point

Idle: 1-1/4 turns in, (from slide just closed)
LSN: 4 turns from closed
MRN: 3-1/4 (10 o'clock)
HSN: 2-1/4 from closed

P4 plug

it will run and idle at above settings.

HSN: will be within an 1/8 of a turn from perfect
LSN: will be within a 1/2 a turn from perfect
Idle: don't move

Good Luck!

The OS 2060 is the best I am using a Mugen OEM 2042 (Its an OS 2060 copy) with a Mugen L shaped header. Best combo I have tried yet. I have tried the dyn 053, dyn 086, GRP 2053. OS 2060 or Mugen 2042 beats them all in power, top speed and torque. I also installed the EB Mods Mugen head button. Huge improvement. Defiantly worth the 40 bucks. You can get them from www.Lucky7RC.com ask for Joe. He is the one that hooked me up with this killer combo.
