I bought a '98 WR400 that was wrecked. The frame was bent, swing arm cracked in half, and the rear shock was sheered. I bought a '98 YZ400F frame to transplant everything onto. On the left side of the neck, there is a silver box with a blue and black wire coming out of it. Is this the voltage regulator or is it something else? The reason I ask is that on the YZ400F frame, there are no tabs for it. I didn't know if the YZ stator is weaker and doesn't need a regulator. If it's not a voltage regulator, it shouldn't need much air flow, so I was going to zip tie it under the tank. If it does need air flow, then I'll have to zip tie it out in the open.
