Bit of a long shot this.
When I was around 16(about 15 years ago!) I serviced a muddy fox that one the the boys used to own. At the time it was the best bike I'd ridden, and to this day remeber how well it rode.
Right now to the nitty gritty!
It was a white frame, with coloured flecks(bit like the Kona's) had a full Deore, could be DX groupset, with from what I remember Araya rims, and it maybe had a T bone stem. It was aound 1990-1991
Anyhelp with this would be appreciated as I'd like to try ansd source one of these in a 16"
Thanks for looking
