Default 911!! Ninja MR21 B01 .21 Engine Factory Needle Settings

Can someone please help me out with the stock HSN and LSN factory carb settings. I bought it used from a guy and want to start off with the factory settings. I understand there is a CD Manual on it, if someone has a link to that I would greatly appreciate it. I am heading for the WORLDS and then to our local track to practice the post that I have found very alot!!

Thanks!!

I would suggest that you just back off both needles about half a turn and start from there.

Just going to open this old topic back up....any idea what the default idle settings are? I've got a second hand engine and it seems totally out of wack and idle seems really odd.
