You left out the fact that in order to use any of the parts you listed on a YZ 450, you first need to replace the crankcases, about $500. the YZ cases will not accept the starter motor, or the WR ignition cover, and has no bore to support the idler gear pin.

Furthermore, the starter clutch must be mounted to a WR flywheel, which will not mount to the left axle of a YZ crank.

Minor annoyances, I'm sure.

I have heard of kits that sell for $800 or so, but I wouldn't know where to look for them.

The best way to get an electric start is to buy a WR450 and mod it into something more like the YZ. It's a whole lot less expensive.
