Yamaha Banshee Dual Carb Kit – Billetron & PRO-SERIES Options | 1987–2006
🔥 Custom-Tuned Dual Carb Kits for Peak Performance 🔥
Looking to upgrade your Yamaha Banshee’s intake system? Our premium dual carb kits are engineered for max throttle response, smoother tuning, and serious gains across the powerband. Each set is sold as a matched pair and includes a 2-to-1 cable designed for OEM-style thumb throttles.
✅ What’s Included:
Dual Billetron or PRO-SERIES carbs (your choice)
2-to-1 thumb throttle cable
Adjustment tool
Optional alcohol setup: billet bowls, dual power jets, high-flow/pump-rated needle seat valve
CNC-machined billet aluminum construction
Precision-tuned metering rod and power jet (Billetron)
Additional torque jet for off-throttle tuning (PRO-SERIES)
🛠️ Important Notes:
Throttle Compatibility: OEM thumb throttles may not fully open larger carbs. For 44mm+ carbs, we strongly recommend a Terry Cable Billet Thumb Throttle (sold separately).
Twist Throttle Support: We do not offer twist throttle-compatible cables. Aftermarket options may work.
Recommended Upgrades: These carb kits pair best with VForce4 reeds, UPP Racing, or Moose manifolds.
Custom Fuel Options: Alcohol carb kits are upgraded with billet hardware and fuel-specific internals.

My 400ex has never sounded better. New tensioner, guides, and chain fixed the noise. Metal bottom end gasket was cool too, didn't rip while working on it.
