Tell me your feedback for the ZR800 efi's. I'm trying to decide whether or not to buy the warrenty that extends beyond the standard 1 year from the factory. It's a 2002 left over from last year and I'm getting a pretty good deal on it. I also know if I modify that will throw the warranty out the window anyways but, I don't plan on doing anything major maybe just a headlight cover for Mikadoo ha ha!!
