Description

● YUMINASHI Denso to Keihin B-Type Injector Conversion Set (16450-KYJ-K26)

● Product Overview

● When pushing your engine beyond factory parameters—whether through a big bore kit, high-lift camshafts, or an E85 ethanol conversion—fuel delivery must scale perfectly with airflow.

● Running a stock injector on a modified engine risks leaning out the air/fuel mixture, pushing the engine to its thermal limit, and causing catastrophic failure from detonation (engine knock) and overheating.

● The YUMINASHI Denso to Keihin B-Type Injector Conversion Set is engineered to solve this.

● This comprehensive CNC-machined kit allows you to seamlessly replace your factory Denso injector with any of Yuminashi’s 20 high-performance Keihin B-Type injectors.

● By upgrading, you secure the fuel volume required to maintain safe, reliable tuning margins for both rigorous road use and heavy track days.

● Precision Engineering & 12-Hole Atomization

● Upgrading your fuel volume should never mean sacrificing combustion quality. Your factory Honda Denso injector utilizes a highly efficient 12-hole spray nozzle to create a fine fuel mist, preventing intake wall-wetting and ensuring a homogeneous air/fuel mixture.

When you convert to our B-Type Keihin injectors, you maintain this critical 12-hole atomization architecture.
This ensures smooth, instantaneous throttle response and clean combustion, even when flowing significantly higher volumes of fuel.

● What’s Included in the Kit:

CNC-Machined Aluminum Adapters: Ultra-lightweight upper and lower adapters designed for a precise, rigid fit inside your factory throttle body.
Precision O-Ring: Engineered to create a flawless, vacuum-tight seal between the B-Type injector and the larger stock Denso injector joint.
Plug-and-Play Wire Loom: A custom wiring harness that adapts your factory Denso wire connector directly to the Keihin B-Type injector, requiring zero cutting or splicing.

● HOW TO INSTALL?

● Simply install the CNC machined aluminium injector adapter on your B-type injector, use a drop of oil on the O-ring to slide the aluminium adapter over the injector.
● Push the cup shaped small CNC part into your throttle body so the B-Type injector will sit in the correct position in your throttle body.
● Connect the B-Type injector with the wire loom in the set to the stock wiring harness of your bike and you are ready to run...

● Baseline Injector Flow Guide (Tested at Honda's 3.2 Bar Standard)

● To select the correct Yuminashi B-Type Performance injector, locate your factory baseline below. All injectors listed utilize a high-efficiency 12-hole atomization spray pattern from the factory.

( ※ Note: When upgrading for E85 or a big bore kit, calculate a minimum of 35% more flow over your factory baseline to maintain a safe Air/Fuel Ratio).
