I've been a sit-down rider most of my life, but just yesterday an opportunity to pick up a 1979 JS440 for less than $100 came across my plate. And I've sort of been looking for a good excuse to experiment with a stand-up ski, and I love tinkering with engines, so I thought this might be a good opportunity to pick one up. Thoughts?

What can I expect from this ski? Is it a good performer, or just an old dog? I would love some feedback on this machine and thoughts about taking it in for project ski. Thanks in advance.
