I had the EXACT same issue on the SV at first.
Hit the starter, and you got "click click click click click" at a rate of something like 4-5 clicks/sec. Sometimes it'd start, othertimes it wouldn't. My case wasn't a case of 2nd time & she fires. Usually the battery would go flat, after around 10 tries, and then there's no hope at all. Stick the battery on charge overnight, back to normal, ride for a bit, and next time you start up, the clicks return.
What was the problem? Stealership had forgotten to plug the Reg./Rect. in and I was such a novice that I didn't even realise the connection was loose to say the least!
With 2 half hour runs, it should be good enough to ram the battery some charge in. I'd suspect your Reg./Rect. is pretty goosed.
