I am looking for some advice on a 96 zr580 efi. The efi is battery powered and i've heard some concern about it. I called my local cat dealer and asked him about it and was told that it was only the first couple of years to watch out for. So if any of you have any experiance with these or any information it would be greatly appreciated. The reason is that this is on a sled i want to buy, and i don't want to get a sled that will be sitting in the shop alot.
