Hello, and thank you for allowing my post to your group. Yesterday i rode in a memorial ride for one of our fallen brothers . I have a 87 heritage .At our second stop ,about a hour after we got there , i noticed i could hear my bike turning over from where i was sitting .As i looked over i saw 4 or 5 people standing next to it so i jumped up and ran over . Not knowing what was goin on . When i got there the bike was cranking over , and bike was in first gear . I had parked rite in front of huge tree , the bike had already scotched itself against tree . A fellow biker was holding clutch so bike wouldnt move anymore . I have a master cutoff switch on bike and i killed power . OKAY , bike ign switch was OFF , motor was cranking over .And also i have a flip up screen radio and it was powered up .ALOT of riders there and no one including myself had ever heard of this kinda thing happening . ANYONE have a clue what could have caused this ???????????
