got a little problem with my 1998 cbr 600f my battery died the other week so I bought a new one (I bought the bike off my mate and he hadnt changed it for about 6-8 years) fitted the new one charged it up and its been fine for a month, but today after a quick run out I came home turned it off and when I tried to start it 10 mins later it wouldn't turn over, the same problem as before. now my neighbour mentioned the rectifier and ive googled it and it looks a easy change but im wondering if the is anything else I need to check or am I best getting the electrics checked, do you guys have any ideas???
