This came on rather sudden. Most likely from riding in sugar sand that got ingested. I'm still riding it and been topping off the oil as needed. In the pass 2000 miles, I've been adding about half a quart every 100 miles. The left plug did foul once but otherwise it runs pretty close to normal. I'm guessing a oil ring? I could tare it down but with 38K I'm looking too save time and find another new (used) bike. Most likely another Versys. I can't figure out how I should get rid of it. How low should I go on selling price?
