Hay, new here, I just acquired a 2009 650 Classic that runs like garbage. I have found a treasure of advice on here and I'm going to play with Carbs the rest of winter. The bike had sat up for around a year and had REAL BAD gas in it. Cleaned it up and used Sea Foam and got it "running"? more or less. Carb clean and new jets (thanks for the advice about wasting $ on kits), so hope it'll work. It is a real sharp bike. And being 74 it fits me and isn't too heavy!
