Will work properly with an XS400 DOHC 12E engine?

Thanks

They all used the same cable connections but you need to check the engine tach drive ratio and the tachometer ratio. I know that Honda's are 1:4 and Yamaha's are 1:5. If they're the same, you're fine, otherwise you'd need a convertor box to adjust the drive to the tach to get correct speed. Or, just know how much it's off and work from there.

To the best of my knowledge, Yamahas all were the same . I have used a rd350 tach on an XS650, and it read right.
