Swapping to a slightly larger main jet generally enriches the mixture under wide-open throttle; a smaller pilot jet alters low-throttle smoothness and idle quality.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eUse larger main jets for richer full-throttle performance after intake\/exhaust upgrades.\u003c\/li\u003e\n  \u003cli\u003eAdjust pilot jets to fix hesitation, popping, or unstable idle at low throttle.\u003c\/li\u003e\n  \u003cli\u003eCarry a couple of incremental sizes to test and revert if performance worsens.\u003c\/li\u003e\n  \u003cli\u003eLabel stock jets before removal to ensure accurate comparisons and easy reinstallation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat comes in the kit and how is it packaged for workshop use?\u003c\/h3\u003e\n\u003cp\u003eThe set arrives with 43 individual jets, sorted by size so you can quickly pick the required diameter during tuning.
