[QUOTE="wfooshee, post: 1302241, member: 6354"] 80 to 85 amps would be a cap for cranking current turning over the engine. If the starter was out and on a bench, 35 amps would be the highest you should see. My starter back in 2009 pegged my ammeter at 160 amps. Had pretty much the exact symptoms Heidi describes: at a gas stop I could count on it being unstartable for 15 minutes or so, but after that you would never know anything was wrong. Starter replacement fixed it completely. The battery I had during that episode didn't last much longer, so spring 2010, I got a new one. That battery is still in the bike. I got a used starter from a forum member. The only way to tell for sure if it's the starter or the battery is to measure the cranking current. If the starter demands more than 85 amps or so, it's got to go. It's a bitch to get to, though. The entire intake system has to come off, throttle bodies included. Once there, the starter is easy: one electrical connection and two bolts.
