160 main jet
3rd needle clip
stock pilot jet
1.5 turns fuel screw.
How did you come up with the settings? I would like to learn how to caculate my own jetting for temp and elevation, but cant find the information anywhere... I found some information on a XLS caculator that was avalable, but no luck w/ the author emailing it to me.
Also is the "fuel screw" the same as the mixture screw that the yamaha service manual refers to?
How much diff. would a 168 (what is in it now) vs. 160 (your recomendation) make?
