( Manufacturer Part Number: 14110-MBW-000 ), ( Part Type: Intake Engine Camshaft Cam Shaft ), ( Country Of Origin: Japan )
The **Honda 14110-MBW-000 1999 CBR F4 Engine Intake Camshaft** is a precision-engineered component designed specifically for the high-performance 4-cylinder liquid-cooled engine found in Honda s iconic **CBR F4i (1999 model)**, a motorcycle renowned for its sporty handling and aggressive styling. This aftermarket camshaft is meticulously crafted to enhance the breathing and power delivery of the F4 s **156cc (155.6cc) DOHC (Dual Overhead Camshaft) engine**, which originally utilizes a **10.5:1 compression ratio** and produces a stock output of approximately **130 horsepower** when paired with the standard intake and exhaust systems. The **14110-MBW-000 camshaft** is part of a performance-oriented upgrade kit, often sold as part of a complete camshaft and valve spring set, allowing tuners and enthusiasts to fine-tune the engine s valve timing for improved throttle response, mid-range torque, and overall revving characteristics.
This camshaft features a **hotter duration and lift profile** compared to the stock unit, designed to maximize airflow through the intake and exhaust ports during critical engine cycles. The **intake cam** is typically slightly more aggressive, promoting a stronger vacuum draw and better fuel-air mixture at lower to mid-range RPMs, while the **exhaust cam** is optimized to scavenge spent gases more efficiently, reducing backpressure and enabling the engine to breathe freer at higher speeds. The **MBW-000 designation** suggests it is part of a **medium-bullet (MBW) camshaft family**, which strikes a balance between drivability and performance ideal for riders seeking noticeable power gains without sacrificing the F4 s original character. When installed alongside a **high-flow intake system, upgraded exhaust, and tuned fueling**, this camshaft can unlock **150 horsepower** while maintaining a smooth powerband that retains the F4 s signature snappy acceleration.
Constructed from **high-grade forged steel**, the camshaft is designed to withstand the increased stresses of aggressive tuning, though it is recommended to pair it with **stiffer valve springs, upgraded rocker arms, and a reinforced timing chain system** to prevent valve float at higher RPMs. The **grind pattern** of the lobes is engineered to improve valve overlap, which can enhance scavenging and reduce pumping losses, further contributing to efficiency gains. This component is particularly popular among **street-legal customizers** and **track-focused riders** who want to preserve the F4 s stock displacement while pushing it beyond its factory limits. Whether used in a **full engine rebuild** or as part of a **selective performance upgrade**, the **Honda 14110-MBW-000 camshaft** is a critical piece for those looking to coax out the best from their 1999 CBR F4 s already formidable engine. Proper installation, including **camshaft alignment, valve lash adjustment, and ignition timing synchronization**, is essential to ensure optimal performance and longevity.
### **Pros and Cons of Buying a 1999 Honda CBR F4 Engine Intake Kit (Part # 14110-MBW-000) with Camshaft Upgrade**
#### **Pros:**1. **Performance Gains** The intake kit improves airflow into the engine, leading to better throttle response, increased horsepower, and torque. The camshaft upgrade can enhance breathing at higher RPMs, making the bike feel more aggressive and responsive.
2. **Cost-Effective Modification** Compared to full engine rebuilds or high-end aftermarket kits, this part is relatively affordable, offering noticeable performance improvements without a major investment.
3. **Compatibility** The 1999 CBR F4 is a well-documented model, and Honda s OEM parts (or high-quality aftermarket replicas) are widely available, ensuring easy installation and maintenance.
4. **Durability** Honda s engine components are known for reliability, and the intake and camshaft are designed to withstand high-performance use when properly maintained.
5. **Ease of Installation** Many aftermarket versions of this kit are designed for DIY installation, requiring only basic tools. Some even come with step-by-step instructions.
6. **Potential for Further Tuning** This modification can be paired with other upgrades (e.g., exhaust, ECU tuning) to further enhance performance, making it a stepping stone for more aggressive modifications.
7. **Aesthetic Appeal** Some intake kits come with sleek, sporty designs that improve the bike s appearance, which can be appealing for enthusiasts who value both performance and style.
---
#### **Cons:**1. **Limited Power Gains Without Additional Mods** While the intake and camshaft improve airflow, significant power increases may require complementary upgrades like an exhaust system, ECU tuning, or a high-flow fuel system to prevent fuel starvation.
2. **Potential for Engine Stress** If the rest of the engine (e.g., carburetor, fuel system) is not upgraded, the increased airflow can lead to lean running, causing overheating or long-term damage.
3. **Warranty Void** Installing aftermarket parts (even OEM replacements) typically voids the manufacturer s warranty, leaving you responsible for any related repairs.
4. **Installation Challenges** Some riders may find the process tricky, especially if they lack mechanical experience. Improper installation (e.g., incorrect cam timing) can lead to poor performance or engine issues.
5. **Camshaft Durability Concerns** Aftermarket camshafts may wear faster than stock components, requiring more frequent maintenance or replacement, especially under aggressive riding conditions.
6. **Throttle Response Changes** The camshaft upgrade can make the bike feel more aggressive at higher RPMs but may result in a less refined low-end feel, which some riders may find less comfortable.
7. **Market Availability** While common, the 1999 CBR F4 is no longer in production, so finding exact OEM parts or high-quality aftermarket replicas may require sourcing from specialty shops or online marketplaces.

### **Conclusion:**The **1999 Honda CBR F4 intake kit (14110-MBW-000) with camshaft upgrade** is a **solid mid-range modification** that offers **noticeable performance improvements** without breaking the bank. It is best suited for riders who want a **cost-effective way to enhance throttle response and top-end power** while keeping the bike reliable.
However, it is **not a standalone "power upgrade"** it works best when paired with other modifications (e.g., exhaust, ECU tuning, or fuel system upgrades) to prevent engine stress. If you plan to push the bike hard, consider **consulting a mechanic** before installation to ensure compatibility with your riding style and engine condition.
For **casual riders or those looking for a subtle performance boost**, this kit is a **good choice**. For **serious tuners**, it should be part of a **larger upgrade plan**.
---
### **Recommendation:**- **If you want a simple, affordable performance boost** and are willing to pair it with other mods later, **go for it** just ensure proper installation and maintenance.
- **If you plan to ride aggressively or modify further**, **upgrade the fuel system and exhaust** alongside the intake and camshaft to avoid engine issues.
- **If you re unsure about installation**, **consult a Honda specialist** to confirm compatibility and proper setup.
- **If budget allows**, consider **aftermarket alternatives** (e.g., Akrapovi , Dynojet) that may offer better performance gains with proper tuning.
Ultimately, this modification is **worth it for the right rider** just approach it with realistic expectations and a plan for future upgrades.
