Mikuni RS34MM Carburetor | Mounts & Filters Kit | 1982-1985 Kawasaki GPZ750

The Mikuni RS34-D21-K Carburetor Kit is the ultimate plug-and-play performance upgrade for your Kawasaki GPZ750, unlocking dramatically better throttle response, smoother and more controllable power delivery, and up to 25% more horsepower over stock. Eliminate flat spots, hesitation, bogging, and sluggish acceleration for good—this flatslide setup transforms how your classic inline-four rides and feels.

Complete Kit Includes:

• 1 set of genuine Mikuni RS34 flatslide carburetors (pre-jetted and tuned specifically for GPZ750 performance)
• 4 engine mount stub flanges (extended length for proper clearance and fitment)
• 4 rubber intake boots with secure clamps
• 4 high-flow cloth/paper dry pod filters (replaces the factory airbox entirely)

Important Installation Note: Due to the longer engine mounts included in this kit, the OEM airbox cannot be retained. The supplied pod filters are required for correct airflow, fitment, and optimal performance—no additional parts needed.

Rebuilding your original Kawasaki carburetors often costs more than this complete new Mikuni kit and frequently relies on questionable aftermarket parts that lead to inconsistent results and reliability issues. This RS34-D21-K package delivers proven Mikuni engineering, superior materials, and immediate, noticeable gains—crisp snap off idle, strong mid-range pull, and reliable wide-open performance.

Fitment Check Required: This kit is configured for 77mm / 93mm / 77mm center-to-center throttle port spacing (between carbs 1-2, 2-3, and 3-4). Before ordering, measure your bike's carb spacing to confirm compatibility. If your measurements differ, contact us—we can discuss custom spacing options or alternatives.

Bolt on this kit and experience the GPZ750 the way it was meant to perform: responsive, powerful, and fun. Questions on jetting, tuning, or fitment? Contact Us—we're here to help! SpeedMotoCo.com
