I sent the xp back for a refund, it started to chatter so bad, and it wasn't due to EMI or electric fence or anything else, I deleted all my programs and it still chattered so bad with the factory programs, I gave up, after reading on the internet from other people about this, they all had different explanations but the one that got me was EX deus email from XP , is it's the x35 coil and maybe an update would fix it, Im done. so I still have my Equinox 800 to go happily on my way. So long guys
