I thought it might be a good idea to share how I was able to fix my seat latch to actually stay latched 
I've only had my 04 Burgman a month so I've been busy catching up the maintenance (fluid changes, valves, etc), when I noticed the seat didn't fully latch. I'd push down on the seat and it made a clicking sound (like it latched) but you could then pull on the rear of the seat and it would open. Not good if you want your under seat storage items to actually be locked up.
I did a pretty good search through the forums and didn't find much that helped so I snapped some pics to explain what I did to fix my latch. I usually don't fix things my bending something with vise-grips (and it's always a last resort) but in my case it work. Your mileage my vary
First pic shows the latch. I noticed the white plastic collar on the release cable has three slots that can be used to adjust the tension on the cable. In my case I needed more slack so the collar was already in position giving the least amount of tension/slack. After lubing and trying various other things I finally bent the gold metal tab that holds the release cable to give the cable just a bit more slick. This fixed my seat latch!

This pic show the washers I added under the seat hook (goes into latch) to shim it out a bit. It looked like this piece needed to be pushed back a bit to engage the latch better.
