Mikuni / Keihin Carburetor Float Bowl Screw Kit – 190‑Piece Set with Storage Case M4 & M5 Hardware

OVERVIEW

This 190-piece carburetor float bowl screw kit replaces worn, rusted, or stripped factory fasteners to restore secure float bowl integrity and prevent vacuum leaks across Mikuni and Keihin carburetors.

Packaged in a reusable plastic storage case, the set delivers precision-fitted metric hardware in M4 and M5 dimensions for reliable engine assembly.

Engineered specifically for Yamaha, Suzuki, Honda, and Kawasaki carbureted platforms, it eliminates missing bolt complications during routine maintenance and full rebuilds.

ENGINEERING & PERFORMANCE

Socket-style hex heads transfer torque more efficiently than soft OEM Phillips screws, significantly reducing driver slippage and head deformation during high-vibration operation.

Hardened metric threads are cut to exact specifications designed to grip aluminum float bowl housings without stripping, extending service life across multiple rebuild cycles.

Each fastener dimension aligns with proven model-specific sizing, ensuring consistent compression and accurate fuel-seal performance every time.

WHY RIDERS CHOOSE THIS

Technicians and independent riders rely on this kit because it consolidates an entire inventory of essential float bowl fasteners into one organized supply, removing guesswork from carburetor disassembly and reassembly.

Swapping out soft OEM Phillips drives for reinforced socket-style hex hardware eliminates stripped heads and driver slip, keeping projects moving smoothly through repeated heat cycles.

The included lockwashers and precisely machined thread pitches guarantee a tighter, leak-resistant seal around fuel bowls, which directly improves cold starting behavior and baseline idle stability.

By covering the most common aftermarket and factory carburetor architectures, this assortment proves indispensable for routine small-engine maintenance and complete restoration projects.
