The 785-24001-P-0 is a brass needle jet from Mikuni’s 389 series, built to fit TM32–TM38 flat-slide carburetors. The P-0 size delivers a richer mid-throttle fuel mixture than the O-series, making it a solid option if your engine needs more fuel during acceleration or when riding under heavier loads. It’s great for smoothing out throttle response and adding a bit more punch in the midrange.
