Hi to all this is my first post on here my brother has bought an 02 xvs650 dragstar which the previous owner has started to Bob. He is having an issue where he charges the battery and when he goes out for a run the battery is not holding the charge and running flat. My thoughts are the stator but is there any known issues with the charging system on these bikes, or indeed any other potential reason for the battery not charging while riding. Thanks for taking the time to read this I'm hoping someone can help
