Hey chunky,
Welcome aboard... great looking Bullet. Always liked that color. Engine looks clean too and I bet that pipe sounds great.
I've had the same machine, just a 2007, for over 5 years and I've used the decomp, like Ace recommended, every time I shut it down. No problems with the sprag yet.
I almost exclusively kick-start as my e-start is pretty terrible. I only use it if I happen to stall in traffic, but it's only reliable if the battery is at maximum charge. If it's sat for a while, sometimes I will use the decomp and give it a few kicks to clear things out before kick-starting, but if you kick to start and use that decomp lever to shut down you should be good to go.
Let us know if you need the kick procedure for these beasts.
