Start Up Problem

[longumd]

Jump start doesn't worked out...

Again I got my battery charged (12.7V), then tried to start just using the motorcycle battery. The same as yesterday, it is one second of B, then A....

So I got the jump start cable connected, my car is not running at all and I even did not insert my car's key in. After getting it connected, the voltage that my car's battery provided it ~12.8V. Then I press the start button more than 10 times, it is all A. I don't see my light get's dim during all these trys.

So I gave up as it's going to rain, the bike's battery is not 12.2V.

Is it an issue with my starter motor?

This reminds me the first time my bike has starting issue. It was after a really heavy rain and my bike did not get convered since I'm out of town. The following few days I attempt to start it several times, it is very similar to the situation now, one or several seconds of B, then all A. I finally got it started on a sunny day, but since then, it's a pain everytime I try to start my bike.

Could it be some parts getting wet? There are series of rains recently.
