thinking its a bad or going bad battery..buddy with 2012 rsv with a 2014 yuasa battery rode for two trips over 300km next day rode to ride for dad in orillia from bracebridge ..stopped...started rode for 15 mins..stopped ,..no go..i thought the same bad stator but was battery dead and stator was good...old saying ..replace battery every 2 years is cheap insurance....keep battery inside house in winter..just my 2 cents
