The Yamaha Rhino 700 is a popular ATV, but performance upgrades are always tempting. One common upgrade involves replacing the stock CDI box to unlock increased power and potentially improved throttle response. Finding a used CDI box in the USA can be a cost-effective way to achieve these performance gains. However, there are several factors to consider before purchasing a used CDI box. This guide explores the options, potential benefits, and things to watch out for when upgrading your 2008 Yamaha Rhino 700's CDI.
Why Upgrade Your CDI Box?
The CDI (Capacitor Discharge Ignition) box is a crucial component of your Rhino's ignition system. It controls the timing and duration of the spark, directly impacting engine performance. A stock CDI often has limitations built-in to meet emissions standards or to ensure engine longevity. Aftermarket or upgraded CDI boxes often bypass these limitations, resulting in:
- Increased horsepower: By altering the ignition timing, an upgraded CDI can allow for a more complete burn of the air-fuel mixture, leading to more power.
- Improved throttle response: A more aggressive spark can lead to quicker engine response to throttle inputs, making the Rhino more responsive and fun to ride.
- Higher RPM limits: Some aftermarket CDI boxes allow the engine to rev higher before the rev limiter kicks in.
Finding a Used CDI Box in the USA
Finding a used CDI box for your 2008 Yamaha Rhino 700 in the USA involves exploring several avenues:
- Online marketplaces: Sites like eBay, Craigslist, and Facebook Marketplace often have listings for used ATV parts, including CDI boxes. Carefully check the listing descriptions for compatibility with your specific model year.
- ATV forums and communities: Online forums dedicated to Yamaha Rhinos often have members selling used parts. These communities can be a great resource for finding reliable used components and getting advice from experienced owners.
- Local ATV shops and repair centers: Many ATV repair shops may have used parts in stock or may be able to locate one for you. This option is beneficial because you can often inspect the part before purchasing it.
What to Look for When Buying a Used CDI Box
Buying a used CDI box carries some risks. Here’s what to check before making a purchase:
- Compatibility: Verify that the CDI box is explicitly designed for a 2008 Yamaha Rhino 700. Even minor model year differences can make a CDI box incompatible.
- Condition: Check for any physical damage, such as cracks, burns, or corrosion. A damaged CDI box could malfunction or even be unsafe.
- Seller reputation: On online marketplaces, check the seller's ratings and reviews to gauge their reliability. Deal with reputable sellers whenever possible.
- Warranty: While unlikely with used parts, inquire about any warranty offered by the seller. This can protect you against unforeseen issues.
