Yes and no. To pass emission to get into certain areas of the world, the bike is running very lean. A good aftermarket exhaust and air filter along with proper jetting will bring the power back. Also, adjusting the valves as they're not usually in spec from the factory. Running these engines lean for to long will cause them to burn valves and pop pistons.
