There's a 12-character limit for move names, though, isn't there? So, there would definitely be reason to change the name of Shadow Strike, given that it's too long. Spectral Strike, unfortunately, is no better. Given it's pretty much a ghost-type Crush Claw, I would suggest something like Shadow Crush or Soul Crush or something like that.
Weight should a bit higher than Mightyena, Absol, and Houndoom. Absol is weighs the most of the three (103.6 lbs), so something like 125.7 for Kitsunoh should be fine, and the hight should be between 3 to 4 lbs.
Metal force I agree with the weight and almost with the height. I am just self conscious because i am six pounds tall (I know i should not be mocking you but i do agree with you outside of units). Kitsun sounds cool but this poke seems more like a unevolved poke.
Remember, 12 letter limit on attack names. Spectral takes up 8 space already, leaving you with only 4 spaces left, minus any actual spacing. Some name suggestions.
Spectre Claw Spectral Cut Mirage Smash (Mirage Fang sounds better to me) Eerie Blow
