A stock CV carburetor is the single biggest restriction on an otherwise healthy Evo or Twin Cam. This KIPA 42mm SmoothBore carburetor replaces it with a straight-through bore and an adjustable accelerator pump, and it bolts on with the jets you need already in the box. Open-box, at a fraction of the branded equivalent.
💡 Why You’ll Love It:
✅ 42mm SmoothBore Body: Straight bore flows more air than the stock CV throat
✅ Adjustable Accelerator Pump: Tune the shot so the throttle picks up cleanly off idle
✅ Bolt-On Fitment: Uses the stock intake mounting on Evo Big Twin and Twin Cam engines
✅ Main Jet Kit Included: 155, 165, 170 and 175 jets for altitude and exhaust changes
✅ High-Flow Air Filter: Matched filter included rather than sourced separately
✅ Mid-Range Jetting Out of the Box: Rideable before you start fine-tuning
✅ Fits 1990-1999 Evolution and 1999-2006 Twin Cam: Covers two decades of big twins

🧼 Care & Use:
• Not compatible with factory cruise control — check your bike before ordering
