I agree with Dave , and there are other differences in the motors ,bore and stroke for sure , that would change redline ,and maybe exhaust header length ( that would effect wavy tuning). I'm not a student of the DR650 , but we know the head design is much better ,doesn't the DR put out about 45-50 horsepower? Lancer's stage 3 cam is designed to work in the Savage the lift is .274 just a bit higher than the stock .254 and this follows what I said above ,it is just slightly more than stock, and is designed to lift higher only to compensate for the area that the valve stems take up in the intake and exhaust ports , showing the makers knew what they were doing. The bike shown above is using a 40mm carb , yet Dave and others use only a 36mm carb to obtain nearly the performance /horsepower claimed of the DR cam ,I would think with smoother running an less problems tuning. So the question is do you want to save a couple of bucks and try the DR cam hoping it will work ,or buy a stage 3 from Lancer knowing it will work ? With the DR cam I would bet mileage to be poor ,the fuel leaving the exhaust pipe unburned ,because the slow speed it is traveling into the head it fails to atomize (swirl) and doesn't burn.
