The 785-23005-Q-4 is a brass needle jet from Mikuni’s 480 series, made for use in VM38 carburetors. Its Q-4 size sits in the middle—richer than a Q-0 but leaner than R-series jets—making it a solid option for fine-tuning mid-throttle fuel delivery without going too rich.
Series: 480 (VM38 compatible)
Material & Origin: Brass, made in Japan
Length: Approx. 47 mm
Outer Diameter: ~6.5 mm at head, ~5.2 mm at shaft (typical series dimensions)
