Yeah, 16k is NOTHING. I'm approaching 20k on my '98 Helix, and aside from normal maintenance stuff, it's needed nothing unusual. At 16k, I recommend the following (assuming you have no history, or this stuff hasn't been done)
(I) = Inspect. (R) = Replace
Engine Oil (R) (Use full synthetic; any will do, and this has no wet clutch, so you can use automotive synthetic oil)
Final drive oil (R)
Brake fluid (R)
Valve clearance (I)
Coolant (R) (Remember; only use Honda coolant, or silicate-free equivalent)
Also check for any obvious oil leaks, rust (indicating it was ridden in the rain or early in the season, when salt is still on the roads).
