Cleaning a KLR250 Carb
Most problems with Kawasaki KLR250 dirt bikes stem from issues involving the engine -- either it won't start, it has a rough idle or it continually backfires. Dirt bikes are prone to these sorts of problems because the carburetors can be affected by the typical riding locations preferred by dirt bike riders: dirt tracks. Dirt can clog up the carburetor, which is why you should inspect and clean your carburetor regularly to keep your dirt bike in proper working order.
