Is there anyone here that is using an EMM needle? Can you post jetting specs please?

Thanks, :)

My specs below in my signature were good for the Stroker Exhaust System at 1000-3000 feet. It ripped. Got caught by the cops with aftermarket LOUD Stroker and had to replace with the stock can. My specs now:

PJ 35, PAJ A little more, Main Jet 150 and EMM Clip 1 (Top) with my Stock euro can. So far so good but havent really tested it.

But then mine is a WR400 1998!!!
