I bought a 2002 Kawasaki Prairie 650 (KVF 650 in Canada) last month for $2200. Probably paid too much for it but it's too late to do anything about that. It has 10050 kilometers on it but it looks like it wasn't ridden very hard. The tires are about half worn and the brakes are a little on the weak side but my main concern is its colossal appetite for fuel. The exhaust has a fuel smell to it, as does the oil. It's a bit tough to start from cold, and it coughs through the carbs until it's warmed up. Apparently if the valves are out of adjustment and too tight, this is the result. I've never done a valve adjustment on anything and I'm not exactly a highly skilled mechanic but I would like to tackle this myself with some help rather than pay a shop to do it. Anyone have any advice?
