Hi all just a quick question for those who might know. Had a problem with the TRX last thursday where it broke it down

At the time we thought it might have been a fueling problem, cos there was a lot of crap in the bottom of the tank and I had had the tank off recently and may have dislodged some of it causing a blockage.
However the battery was fully discharged as well which we put down to constent attempts to restart.
So I recharged the battery popped it back in started the bike up, but nothing happened ....

Right ... Took the battery back out, got it on the charger and the battery is fully discharged again.
Now is this a fault somewhere in the electrical system causing this is it just that the batterys feckered?
Any ideas anyone?
