I am selling a CDI off a 1999 XC 600. This is a good working unit that was replaced with a 700 topend and CDI. This will work on any domestic big block 600 twin. There were a few made in 1997, 1998, 1999 and I know of a few more models made with this motor in 2000 and 2001 but check as this won't work with the valved 600's. It's yours for $60 plus shipping.
