thanks for all the replies Lads, I pulled the plug out of the socket on the bike and put it back in again and within a couple of hours the battery charged up again and started the bike easily. Ive taken the battery off and left it on a shelf not attached it to a charger for the last 2 days and it hasn't dropped charge. I know the bike alarm will sap charge but if its got the trickle charger running should it not be ok? fook knows! I'll put a motobatt on it as suggested and see what happens...newer bikes are a pain in the arse aren't they!
run tender from pigtail all problem will be gone
