hello, my battery keeps dying on me, even with a full charge it doesn't last. when I charge it, its ok. Then dies after a few starts. I did notice a LOT of condensation in the clocks. I'm wondering if this can case a short and drain the battery?
Anyone else have a similar experience?

Sounds like the regulator or recifier isn't working properly.
Check the voltage on the battery with the engine running. It shoud be around 14V. Any lower and it's probably not charging, any higher and it's over charging and wrecking the battery.

either that or the alternator isn't returning a charge, bad earth, cold weather draining the batt if stood for a long time, check the condition of the cables, i had damp in mine (had a green tinge to the wire) and caused havoc with mine

14.6v for a healthy charge and that should be across the whole rev range. I have a charging system fault finding guide somewhere.will dig other out for you later

If you could that will be great! it fluctuates between 11.9 and 12.0 at the moment. But its now smoking intermittently from underneath the tank! :/

Smoking? not good....

Melted wiring perhaps?

There is a 5 pin connector which has the 3 outputs from the alternator plus a crank sensor output, they get corroded and can get hot and melt. Some have done without the connector altogether and hard wired it out. I imagine if you split it you will find some of the connections looking worse for wear.

I have pinched this pic to illustrate, but gives you the idea
The connectors between harness and reg rec are also less than great, but more near the tail unit
