1977 Bonneville 750
I am a very new owner of a 1977 Bonneville 750. I’ve been struggling with kick starting it and it seems to be related to a weak battery. The photo below is the battery that was in the bike when I bought it a few weeks ago. I want to replace it - what’s the recommendation for an appropriate battery for this bike - I want a good one, not necessary a cheap one. Many thanks in advance to the help.
