stock 2006 jetting

Searched around everywhere and cant seem to find the stock jetting specs for the 2006 yz 250, n3ej needle. 

 

I have been using the n3ew needle, but want to try the stock  '06 settings. 

 

Thanks

I can tell you that the stock pilot is 50, but I can't remember what size the main is.

Looking at the manual for my '07 YZ250 (should be the same as yours...), here are the stock specs:

 

178 Main

50 pilot

N3EW Needle, clip in 2nd from top

I think my 06 came stock with the J needle installed.
