I have 2009 750 my clutch lever seems to be a little bit loose but no troubles shiftting gears or anything, how can i get it back the same way when i bought it brand new?

Loose? Like it wobbles up and down, or it wobbles in and out?

If it's in and out, there's this little silver twisty thing (called the clutch adjuster nut) near the clutch lever that you can use to put more tension on the cable. Just keep in mind that you don't want TOO much tension as you might reduce the life of your clutch cable.

It's gonna look kind of like that, but slightly bigger.

What about if it's wobbling up and down?

Mine does the same. The general consensus (I've taken it to a couple different shops for various things, and they both gave me grief about the clutch lever) is that my aftermarket clutch lever is made poorly, and therefore doesn't fit properly. If you've an OEM clutch lever, I'm not really sure...

Buy a good quality clutch and brake lever, like ones from Pazzo, and you will be happy.

Flame away. Based on that pic which one do you twist to add some tension? The washer shaped one or the bigger flatter one?

Well, luckily for you, that was just the closest thing I could find -- I don't even know the answer to that question, myself. Here's what the suzuki GSX-R adjustment nut looks like, it is all one piece.

Alternatively, see the photo attached.

Once again, don't over tighten the thing -- will put unnecessary strain on the clutch cable.
Edit -- If you're like me, and buy a used bike and this thing requires pliers or some other tool to turn, that's not right. I was shocked when mine snapped in half. It should easily twist by hand.
