Sounds like a T140 if it's a 750. Big bore kits were/are available for earlier 650 T120 engines but the price would point at a standard T140.
It's not easy to estimate the cost of getting it back on the road until you can have a look at it.
If it's not in bits in boxes, not mostly rust, it can be kicked over (ie not seized) then sounds a good price although I'm not up on prices in Canadia. A quick check on ebay or craigs whatsit should tell you where that should be.

 

It'll always be worth 2500. Just buy it.
You'll need to get to the sludge trap if you want to keep and ride it. It's not going to be a bit of T-cut sort of bike. A bag of spanners willl be required.



That's a sludge trap in the crank of my last T140 build that needed a bit of a clean
