Hi there, Not long ago i got a new Sherco 125, i took the plug out the other day to see what it looked like and it was really black! So obv it needs more air, but i don't know which way you screw the air mixture screw to make it leaner? If anyone could tell me it would be great. The carb is the standard Dellorto.
I had a feeling that it is out?
Also because this is my first NEW bike i was just wondering whether you usually have to fiddle with them to get them right? for example the mixture screw. I have greased all the bearings etc.
Many Thanks!!
