250 2C jetting ?

[jamesf]

Hi, new member here. I didn't see a 250 specific forum

My 2C is running poorly, and while there have been some non-stock jetting adjustments I need to correct, I'd like to if anyone has better than stock jetting recommendations. In particular, the E51 needle looks rather useless, very much like my USA-emissions spec Alazzurra needle.

thanks,
jim
