How much should I sell my motorcycle with a blown engine for?

You are in limbo with this one. Your bike is too old to be worth fixing but not old enough to be collectable.

Option 1 - get a used motor from the wreckers if you can fit it yourself

Option 2 - Sell the complete bike as a non-runner - easiest option but you won't get much for it

Option 3 - Wreck the bike yourself - Stuff like forks, gas tank, instruments are always in demand as that's what people break when they crash. You should easily get $500 just for those parts but it may take time to find a buyer and you'll be left with a semi-cannibalised wreck lying around the shed - possibly for years

Fix It. It cant be more than a stuck/burnt valve with zero comp. (or slipped timing chain--new chain/tensioner). If you can show it runs, it Will sell.

If not, its catch-as-catch-can. If you wait long enough, someone will buy it for what you ask. 'Till then, U you will loose patience and sell to next guy who has $50, cash.

I paid $300 for a Honda with only 1300 miles on it. Needed new tank, battery, TLC. Had her 8 years..

See what they're going for on eBay. Five hundred sounds about right. And if that doesn't work, you could lower it further. I've got a non-running 87 Honda 250 in my garage. In my case, it's a parts bike for my new Honda Rebel.

Whatever you can get for it. Once a bike doesn't run the price goes through the floor.

There was a reason why the bike was parked and you can be sure it didn't fix itself sitting the barn. Unless there is a major reason to restore it, like it being your great granddad's 1923 Indian, it is not worth more than salvage value and definitely not worth your time spent disassembling, advertising, answering replies, etc.

Sell it for scrap and move on.

I wouldn't pay more than $200 as a parts bike.

It won't bring much. Start at $350 on craigslist and then come down when you don't get any calls.

Jan 2012, sold my 2000 Suzuki 650 Savage -- non-stock pegs/handlebar/headlight/taillight/seat; not running -- for $400.

Sell it to a scrap yard. They should give you a couple hundred for it
