The green one is a 440. Looks complete. Seems to have good compression. The other black 580 was used for parts. I dont know a ton about them. There are a ton of parts or make them runners. I do not have the titles for them. I got them from a neighbor who was moving. I dont ride sleds anymore. Package deal must take them all. Mainly looking for cash or trade fir 3 wheels or other motorized toys. Come take a look. North end of Redmond. Thanks for looking
