i went down to start up the bike today. i just put the battery back in it yesterday. it was on the trickle charger all winter long. now the bike won't fire. i am waiting for the father-in-law to come check it out, until then i thought i'd get advice from my gang here. all the lights come on and it sounds like it is gonna fire, but then it makes this horrible grinding sound coming from right around the battery area. what could it be? i put the battery back in myself this year, usually i have my husband do it (i am trying to be more self-sufficient this year). did i do something wrong? i hooked it up just like the book said, red +, black -. anyways, this puts a damper on any riding i wanted to do today. thanks for your help gang. :twfrox:
