Hi guys, I have a BERG FS 650 E 2004. I live in Mexico City, 2200 mts over the sea level and I would like to know if anybody has a needle jet level tab reference depending sea level. I know right now I am over idel mixture (too much gas), I have readden in the owner manual it is in the 2nd of 6th position starting from top, it means I have just 1 position to reduce gas flow on the 160 yet, is it enought or I need to reduce jet too?
