For starters check that all the jubilee clips are done up firmly on all the pipes, they can come loose over time.
You really need to pinpoint where the fluid is coming from? The thermostat cap is at the front towards the right side under the tank, so make sure everything is tight around the housing area, or it may even be that the cap has undone itself. Unlikely, but check it anyway.
Normally if the system is all clogged up the fluid will boil then get dumped out of the overflow of the expansion tank, but that would go down a pipe onto the floor, so i'd guess either something is not done up tight enough, or maybe a split pipe?
If you top up the coolant then let the bike tick over with the tank safely raised then i'm sure it will only take a few minutes before it starts chucking it out again and you'll see where it's leaking from, that's if you can't see anything else that looks wrong beforehand.
