I am looking at the power up kit for my son's 2005 crf150f. I see Powroll has a simple yet extensive procedure to find the right settings. I am in central texas at roughly 1000ft elevation. I will go with the lower elevation main jet but does anyone have a recommendation on the needle clip setting? And I saw that someone mentioned an air bleed??

Ive heard to use the 4th clip position
