Message: [QUOTE="jmics, post: 1067983, member: 68887"] I am going to throw a fly into the ointment here. If I am not mistaken the wr 250 exhaust camshaft timing is advanced compared to the YZ which really kills the power potential of that engine(I know this to be true of the 450). the yz and the wr are extremely similar with the wr being based on the yz but detuned,wide ratio gearbox,and electric not only for starting but for lights also. If the wide ratio gearbox and lighting is of any importance to you it is cheaper to get the wr and set the engine up to run like the yz than it would be to buy a yz and add lights and wide ration gear box.
