The early 90's was a classic period for MTB's, I'm rarely excited about anything from the late 80's
and post 96/97 they leave me cold.
Personally I've never owned or for that matter ridden a Kona but always though they looked great and there's plenty of love for them on here so I'm sure you'll get more comments from far better informed members than me.
As for being to scared to ride it, don't be its a great looking rig but its not a long lost "unicorn" you've stumbled upon.
You might benifit from fitting some newer rubber and saving those tyres, they're mostly certainly not a supple as they used to be, and it would be a shame to kill them off.
I guess since its almost catalogue spec you have little plans to change anything aside from fitting some pedals ?
Post some picture of it out and about and a little muddy
