I have one I picked up at the end of last winter for $150, wasn't running. In about 3 minutes I discovered a crack in the main fuel feed off the tank, replaced it and it fired right up. I was told it was a 91 440 XCR but discovered they didn't make the XCR until 92. A quick google of the model # off the side revealed it was a 91 XC 400. Someone peeled off most of the decals and painted "XCR 440" on the hood and the seat isn't original. Everything else is but was in pretty rough shape. I disassembled the entire front end and sandblasted all suspension parts, painted black (they were red but I couldn't find a matching paint) rebuilt the shocks, rear suspension, and all new bearings in the driveline. New hoses, waterpump belt, recoil cord, hyfax, fuel/oil lines, clutches etc. Going to ride it for the first time this weekend. I wasn't looking for an extra sled but a guy I work with had it and wanted to get rid of it since his kids were grown up and out of the house. I can hardly wait to try this thing out. Attached is a picture of it. I have since replaced the seat cover since the one on it was ripped.
