if I average the 200-500 then add to the next two values....then divide by 3, I get 783$...ok now if figure it's worth 8200$ after I put in 150 hours of my time at 55$ an hour= 8250$ and buy some new tires at 150 each...8250 +300= 8550$....(not counting the heating and lighting bill for my man cave)
You are correct with your assessment of hours in a project. If you are a hobbyist, the hours spent working on a project can be great therapy and as we age, it keeps your mind sharp. You can also trade the hours spent building a bike with the hours you'll, hopefully, spend riding it. For me, even after all the bikes I build, nothing compares to the pleasure of riding what you built.
As for hours spent on a bike, to get from here...
To here...
Was about 120+ hours. Not including parts hunting trips.
If you value your time at your professional rate then it implies that this is purely a business transaction and not one of passion and it is likely not worth the walk.
I paid about $1500 for a V7 Sport in similar condition to that of Joe's before picture. Reading this thread I am wondering if I was really taken in this deal and have concluded that I was not. I have a bike that got me started on Moto Guzzi in the early 80s and when it is running and looks like Joe's after pics, I will have a lot of enjoyment and fulfilled a long time dream.
So as to value... I think paying up to about $2k would not be unreasonable depending on what your intent really is. If your intent is to pay the bills by redoing it you have already shown that is a dicey proposition. Either way if you could get it for less than a grand I think it would be a great deal.
