Gimme that man card!
DUDE, there are millions of bikes out there.
This is one that will not give you much riding pleasure, and you and it will be mocked long after you sell it.
Ever notice how there isn't much out there that doesn't have 5 or 6 gears?
This was built to be chick bike, so she could go riding with him.
I would be very suspicious of expensive repairs to a low volume bike that is nearly 30 years old-think repair parts. I further suspect a very low price when you want to off it, if you can sell it.
There is a **** ton of reliable, medium size engine jap cruisers, that are easy and cheap to fix, but probably will never have to be. Decide on a few examples of a more recent high volume popular model, up around 650-750cc's, with low miles at a reasonable price, and pursue all avenues of finding them. Being a fish striking and at a cheap CL ad on a sparkly, very undesirable bike will not make you happy.
Don't do this to yourself.
