I've spent all weekend searching (this and other forums), and haven't found a single solid solution.
Bought the bike about 2 months ago. The owner said the bike sat for a while, and the battery was dead. He charged it, but told me that he wasn't sure how much life was left in it, as he'd never replaced it in his ownership (was second owner). I ride the bike at least every 2-3 days, and the longest it ever sat without being started was 5. A few times over the first month I would try to start the bike, but the battery would be slow to crank, and not fire. Push starting it, the bike ran fine. After the third time of this happening, and getting tired of push starting, I said screw it and got a new battery.
I sprung for the $150 Megaboost battery sold at Cyclegear, after hearing great reviews. Bike started up great, ran fantastic for about two weeks. Three days ago, however, I went to start the bike in the morning and nothing. Press starter, and a single click, but nothing. Push started, and rode to work. Same thing happened at the end of work. Thinking I got a bunk battery, I returned the one I got to Cyclegear and got a new battery and charger. I charged the new one for 5ish hours, until it read 12.8v and installed.
Unfortunately, same thing is happening, even with new battery. Single click from the starter relay, and nothing. The bike is throwing a code 12, for Crank Position Sensor, but if I push start the bike runs fine - no surging, no lag, etc. Battery is reading 12.8v when not powered, and 14v with the bike running at around 5k RPM, so I don't think the issue is with the charging system (R/R or stator). The 50A fuse under the seat was corroded to hell but I replaced that. Now it's clicking/buzzing like a mother, but still no cranking.
I tested the R/R and stator according to the manual, and everything checked out normal. I've ordered a new relay, hoping that's the issue, which comes Tuesday. All electrical connectors are tight and no corrosion or burn marks. I can't find any shorts on the wiring, and the ground strap from battery to engine is fine (no corrosion or burns). All fuses are good.
At this point I'm at a loss. I have no idea what to do next, but I'd like the bike to run again... Where else should I check? Lots of people have starting issues, but most common answer is battery.. I've tried three batteries now and they all don't work. Jump starting from a car battery, with engine NOT running (as recommended) results in the same problem. Jumping the terminals on the starter relay also doesn't start the bike.
Anyone with similar experiences? Someone talk me down from the ledge? :boom
