Anyone have there carb off and apart yet? I need to know what stock jetting is main and slow jet. From what I can gather it should be a #185 main and a S45 slow jet.

The Aprilia parts diagram for the RS 125 USA-Race shows:
Main Jet 175
Idle Jet 45
Needle D53/2A

Mine has a 40 and 175. I wonder if my problem is the 40 slow jet? If anyone has taken there carb apart I would still like to know what jets they have.

I am still looking to see if anyone else has had there carb off and seen what jets they have. I have a #40 slow jet and a 175 main jet.
