2008 Yamaha Rhino 700 CDI Box Upgrade: Used Options and Considerations
The Yamaha Rhino 700 is a powerful machine, but some owners seek to enhance its performance further. Upgrading the CDI box is a popular modification, offering potential improvements in throttle response, top speed, and overall power. However, choosing a used CDI box requires careful consideration. This guide explores the benefits, risks, and factors to weigh when purchasing a used CDI box for your 2008 Yamaha Rhino 700.
Why Upgrade the CDI Box?
The CDI (Capacitor Discharge Ignition) box controls the ignition timing and spark delivery in your Rhino's engine. A stock CDI box is designed for reliability and adherence to emissions standards, which can sometimes limit performance potential. Aftermarket CDI boxes often offer advanced ignition curves, allowing for more aggressive timing and increased power output across the RPM range. This can translate to:
- Improved Throttle Response: A more responsive throttle, leading to quicker acceleration.
- Increased Top Speed: Potentially higher top speeds, depending on other modifications.
- Enhanced Power: A noticeable increase in power throughout the powerband.
What to Look for in a Used CDI Box
Buying a used CDI box can save you money, but it also carries some risks. Here's what you should prioritize:
- Known Source: Buy from reputable sellers with positive feedback. Avoid unknown sources or suspiciously low prices.
- Warranty: While unlikely with a used part, inquire about any warranty offered by the seller.
- Visual Inspection: Carefully examine the CDI box for any physical damage, such as cracks, burns, or corrosion. These can indicate potential internal issues.
- Testing (if possible): If the seller allows, test the CDI box before purchase to ensure it's functioning correctly.
How Much Does a Used CDI Box Cost?
The price of a used Yamaha Rhino 700 CDI box can vary depending on its condition, seller, and specific model. You might find options ranging from $50 to $200. Remember to factor in shipping costs.
Are There Risks Associated with Using a Used CDI Box?
Yes, there are several potential risks:
- Unknown History: You don't know how the previous owner used or maintained the CDI box. It may have experienced extreme conditions or improper installation.
- Hidden Defects: Internal damage may not be immediately apparent. A seemingly functional CDI box might fail prematurely.
- Compatibility Issues: Ensure the used CDI box is compatible with your specific 2008 Yamaha Rhino 700 model. Different years and models may have different CDI boxes.
Can I Install a Used CDI Box Myself?
While it's possible to install a CDI box yourself, it's advisable to have some mechanical experience. Improper installation can damage the CDI box or other components. Consult your Rhino's service manual for detailed instructions. If you're unsure, it's best to have a qualified mechanic perform the installation.
What are the Alternatives to a Used CDI Box?
Instead of a used CDI box, you could consider:
- New Aftermarket CDI Box: This offers the advantage of a warranty and a guaranteed functioning unit.
- Refurbished CDI Box: A refurbished CDI box may provide a balance between cost and reliability.
Conclusion
Upgrading your 2008 Yamaha Rhino 700's CDI box can offer significant performance gains, but purchasing a used unit requires due diligence. By carefully examining the box, verifying the seller's reputation, and considering potential risks, you can increase your chances of finding a functional upgrade at a more affordable price. However, weighing the cost versus a new or refurbished CDI box is crucial for maximizing long-term performance and reliability. Remember to always consult your owner's manual and seek professional assistance if needed.
