The 785-24001-R-4 is a brass needle jet from Mikuni’s 389 series, designed for use in TM32–TM38 flat-slide carburetors. As part of the R-series, the R-4 size flows more fuel than most O, P, and Q jets, making it a strong choice for setups that need a rich mid-throttle mixture. It's ideal for highly tuned engines or riding conditions that demand maximum fueling during acceleration.
