Update
I've just checked the battery and th eresults as follows:
Idle - lights off - 13.61
Idle - Lights on - 13.52
Lights off 5000 revs - 13.34
Lights on 5000 revs - 13.13
Does that make any sense to anyone?
Any help is greatly appreciated as I plan to go to the Glencoe Massacre (Scottish Forum) and want to make sure my bike is ok as I don't want it packing up on me.
Thanks
