you can prob make some decent money parting it out if its rare.
Absolutely not! Keep it. Just take your time and restore that thing and many Yamaha Dealers or collectors may want to buy it.
Many times I have considered buy a used motorcycle and when I see a lot of parts stripped off of it, I walk away because i know all the work it takes to go find all the missing parts. One big easter egg hunt. Forget it.
It is worth more and will sell quicker when you leave it all together.
Many people start adding up the cost of all the parts and figure they can make a lot by selling all of the parts but you know many of those parts are not needed very often,like the swing arm. The owners can rebuild a swing arm with new bushings. They do not need a new one. And if they buy a used swing arm it will need rebuilding too.
So what you end with when parting out a bike is a lot of parts no one will ever buy.
And some people WOULD buy the parts if they knew you had them, but who can afford to advertise them for months? That costs money too.
