Boyesen Rad Valve Reed Cage Assembly RAD-10E — Kawasaki KX85 / KX100 / KX112 / Suzuki RM100 2001-2025

Product Description

Unlock maximum two-stroke performance with the Boyesen RAD-10E Rad Valve Reed Cage Assembly. Engineered for mini-racers looking to dominate the track or trail, this premium upgrade is a bolt-on solution designed to deliver a massive increase in torque and peak horsepower. By maintaining peak flow velocity through the entire valve intake tract, it seamlessly redirects the incoming air-fuel charge for a perfectly even distribution directly into your machine's cylinder intake ports.

Constructed from rugged, one-piece cast aluminum, the Boyesen RAD valve features a specially-designed aerodynamic reed cage that houses their patented dual-stage carbon fiber reeds. The unique multi-stage design allows the top reed petal to open quickly for crisp, immediate throttle response at low RPMs, while the bottom petal opens fully to flow absolute maximum air at higher revs. This results in quicker, sharper throttle transitions and robust pulling power throughout your entire RPM range without requiring any irreversible engine modifications.

Frequently Asked Questions

Q: Will I need to modify my stock airboot or cylinder to install this valve?
A: No, the Boyesen RAD-10E features a bolt-on architecture that replaces your original equipment assembly effortlessly without modifying anything.

Q: Do I need to changes my carburetor jetting specifications after installation?
A: Because the Boyesen Rad Valve increases airflow efficiency so drastically, you may need to tweak your main or pilot jets slightly depending on your elevation and current configuration to optimize the performance gain.

Q: Are replacement reed petals available down the road?
A: Yes, Boyesen supplies standard replacement multi-stage replacement petals so you can maintain peak sealing efficiency over hours of hard racing.

Expert Pro-Tip: When installing your new Boyesen Rad Valve, always ensure the mating surfaces on the engine cylinder casing are completely free of old gasket material before reassembly. Use a fresh gasket and apply a precise cross-pattern torque to the mounting bolts. Over-tightening can warp intake assemblies, so check your manufacturer specs—typically around 6 to 8 foot-pounds for standard 6mm intake flange hardware.
