Convert 2004 sportsman 700 efi twin to carb system?

My 2004 700 has a bad asm harness for the fuel injection system and Polaris doesn't make it anymore the dealer is stuck as how to fix, has anyone converted an efi system back to a carb system?

Not sure if it has been done or not, but I would guess it would be expensive. You will obviously need the hard parts. Carb, fuel pump and fuel lines, choke cable and throttle cable. But also I would speculate that you will need some different harness parts and at least the ECM.

Has the EFI system changed that much over the years. Would it be possible to use some of the parts from a later model EFI system to make it work? Not sure how long they made the 700. If the hard parts are good, then maybe something from a later 500, 600 or 800 might work.

When I read the subject I thought WTF? Why would anyone want to do that? Now it makes sense, but see below.

Good point. Best case, they should be able to salvage the good parts of your harness and repair the damaged parts. Worst case, they should be able to build a new harness.

Additionally, looking here I don't see any "discontinued" parts in the electrical section. I'm not sure what the "ASM Harness" is though. At the very least, I've found ebay to be a good source for old parts from part out machines..

I wonder if they're trying to get you to upgrade to a new machine.
