Well I removed the V-Twin from the Shadow because of a small coolant leak caused by a bad front head gasket. *@!&*#!
The coolant in the overflow and the radiator was a lil’ grody and should have been drained before being allowed to sit for so many years (the bike had 5K on it when I ended up with it a lil’ less than a year ago and hadn’t been inspected since ’86). I’ve ordered an Athena gasket rebuild kit for the thing and will tear it the rest of the way down when I receive it.
