I found this CDI box for the 500 HO and wanted to know has anyone used one on your HO? http://www.magnumtuning.com/en/detail/revolution-pro-atv-speed-rev-limiter-cdi-box/cf-moto

I browsed the website for this device.  I would not install that on my machine even if someone paid me to use it.  There is one model listed for every machine.  The description is written in broken English and the reviews are obviously fake.  There is no way I am going to cut open my ECU and solder some junk onto the board.  Stay away.

Cool, thats why I ask to see if one knows or had it. I have bought 360 degree racing spark plugs on Amazon from Magnum Tuning and they are legit. Gave me great throttle control, and uses less fuel now. Then I saw this item and it had Magnum Tuning on it so I checked to see if anyone used it on there CForce. Thanks

I'll keep a new ECU ready for you on the shelf .
