i have a 2000 r6.

thats failing to hold its charge, i have had the battery tested and it charges and reads fine.

but then a after 8-9hrs is flat and fails to start ..... is it the battery or more likely the alternator ??

any ideas

Thats gonna be ya batt, you can test tha alt by starting the motor,with the lights off,put a multimeter on the bat,try to hold the revs at 3k, meter should read 13.8 v to 14.2, if you dont have a m/meter,a indication that the alt is charging is to turn on the light then rev the motor to 4-5k light should get brighter
