Mikuni MZ Skorpion 660 | Mikuni TM40 Pumper | Single Carb Conversion Kit.

Mikuni TM40 Pumper Flatslide Single Carburetor Conversion Kit — the ultimate performance upgrade for MuZ Skorpion 660 models (powered by the Yamaha 660 engine), delivering massive gains over the stock twin-carb setup.

This kit is also a proven favorite for single-carb swaps on bikes like the Honda XR600/XR650, Suzuki DR650, Kawasaki KLR650, various KTM models, and other Yamaha 600/660 singles — especially when your OEM carbs are worn out or plagued by common issues like poor starting, hesitation, flat spots, or bogging.

Experience the transformation: Say goodbye to frustrating hard starts, throttle lag, and power flat spots. Instant throttle response, smoother power delivery, and serious torque/horsepower increases mean you'll likely wheelie in an extra gear or two. Hold on tight for that first full-throttle test ride — it might try to buck you off!

Kit highlights (Basic version for pod filter use — pod not included):

• Genuine Mikuni TM40-6 pumper flatslide carburetor (with accelerator pump for crisp, hesitation-free acceleration).
• Custom PA11 carbon fiber-reinforced nylon 2-into-1 manifold, complete with mounting hardware and gaskets for perfect fitment.
• Heavy-duty rubber engine mounting sleeve with clamps.
• 1/4-turn quick-action throttle.
• Push/pull nylon-lined throttle cable set (lubricate during installation for smooth, long-lasting operation).
• Pre-installed jets optimized for common conditions, plus spare main jets for wide-open throttle (WOT) fine-tuning.
• Cable-operated choke (rarely needed) with universal mounting bracket.

Fuel economy note: You'll burn less fuel than with worn stock twins when riding sensibly — the improved efficiency shines through. But with all that extra power and torque at your fingertips, it's tempting to twist harder, lift the front, or break traction. More horses mean more "hay" (fuel) when you let them run free!

This upgrade unlocks the full potential of your bike, making every ride more enjoyable and responsive. Proper tuning (considering altitude, climate, fuel, exhaust mods, etc.) ensures it stays dialed in for years.
