Good looking bike bud. Very sorry to hear of your loss. I hope you have been able to find some peace...
If it is as clean as it looks, I'd ask $4500 to $5k for it and see what kind of offers you get. A lot of the value depends on what time of year you sell it. The further past May you get, the less they are worth. Its the old supply and demand. You would likely get $4000 cash pretty quick if were for sale today.
