My bike has problems with starting with the e-start. It's been happening for a while, so I've just been kickstarting the bike. I charged the battery overnight and the e-start worked great... for about a week. In that week I put new blinkers on and an LED license plate illuminator; I used the battery a lot during the week so it's no surprise the battery was weak. I went to start the bike and it cranked over a couple times then just clicked. I can kick start it no problem. When I ride it for an hour or so it'll start up a 1-2 times with the e-start, but then will just click like the battery is dead. This tells me the charging system is doing it's job... well, for the most part. At idle the bike charges at 13.8v, and at 5krpm it's just over 14v. Tonight I went out and bought a battery tender (not that brand, but a similar brand). I hooked it up to the bike and let it charge. After about 5min of charging it said the battery was charged. I confirmed with a multimeter and it was at 12.87v. I hit the e-start and only got 2-3 cranks and then clicks. I tested with the multimeter and it showed 12.6v. Then I hooked up the multimeter to the battery and hit the e-start... the battery goes to ~0volts as it attempts to start. Funny thing is, when you let the battery sit for a minute or so it goes back up to 12.6v. Try to start it off the 12.6v and it only clicks. You think I need a new battery? If not, any ideas?
