I have a mint 04 YZ450 sat in the garage,and have recently broken an 03 WR450 so have the WR engine(bare engine-no starter etc) also sat in the garage. I love the YZ chassis but find the motor is only any good for motocross.I am looking to build a hare and hounds/trail bike,It doesn't need lights,doesn't need registering.But it must be light,reasonably powerful and preferably have a 5 speed wide ratio box. I don't mind kickstarting,If the bike is jetted right and you have the right technique,there is no reason for a bike to be hard to start. So obviously I am looking at putting the wr motor into the yz chassis. I have read all the posts about blanking the starter hole and using a battery eliminator. Would I be able to use the stator/wiring/cdi from the yz? thus eliminating the need for the batt eliminator and starter plug. Or would I need to use the stator/flywheel and casing from the yz? I think with the standard wr cams and the yz carb/airbox etc it would make an awesome off road bike.
