NEEDLE JET

The 785-24001-P-4 is a brass needle jet from Mikuni’s 389 series, made to fit TM32–TM38 flat-slide carburetors. With a P-4 sizing, it delivers a noticeably richer fuel mix in the mid-throttle range compared to smaller P-series jets. It’s ideal for setups that demand extra fuel—such as modified engines, cold weather riding, or higher elevation tuning.
