Well for the entire season last year I was having an issue with my battery/starter. Sometimes it would fire right up with a touch of the button and others it would almost instantly drain the battery to nothing. I finally had some free time today to look into it and after checking all connections and whatnot I decided to pull the starter off. After completely disassembling the starter motor itself I noticed what looked like a lot of charred bits in the endcap of the motor. I cleaned everything up, checked all measurements to be checked, and threw it back together. I put it on my bench with a battery and ran it just to see what it looked like. Well sometimes it spun normally, sometimes it spun very slowly, and sometimes it would jump around, but every time it got alot hotter then it should. I've come to the conclusion that my starter is toast and need a new one but I really don't want to spend the $275+ that everybody wants for them. Is it common for these things to go bad? Would I be safe buying a used one off of eBay? Any kind of help or direction you guys can send me in would be greatly appreciated. By the way, we're talking about a 2008 WR450F here.
