By looking at the parts microfiche, it appears that both tensioners are identical if the drawings are correct. It also appears that they use the same tensioner as the Fourtrax 300, which I think is the same tensioner that Honda uses with all their overhead cam engines. My guess is that it will work, but like Submarine, don't hold me to it.
I only have the 650 manual, so I can't really tell by that.
