Can anyone tell me what the stock jettting specs are for a 2005 ktm 400 exc?
It was wrong.
Sorry I don't know what it was besides it was not good. The biggest problem is in the needle. Not enough tapper.
main : 178
needle position: 1st from top
mixture control screw open: 1,25
Problem is that needle! "D" taper (3rd letter) is too little taper!
