  1. I have a '00 YZ 426 that spun the oil pump gear cracking the cases and damaging some of the gears. I purchased a '99 WR 400 engine and have it all bolted in. When plugging into the CDI box I discovered that there is an extra wire (yellow) that the WR's have that the YZ's don't. The wire comes from the pickup coil. Does this wire plug into the voltage regulator for the WR's? Can I just change out the pickup coil and use the one from my YZ?
