The 785-24001-Q-4 is a brass needle jet from Mikuni’s 389 series, built for TM32–TM38 flat-slide carburetors. With a Q-4 size, it delivers a slightly richer mid-throttle mixture than a Q-2 but still leans out compared to the P-series jets. It’s a great option when you want to improve throttle response while maintaining a fuel-efficient and controlled midrange.
