sounds like you bought a bike that is too bi for your body... you may be able to install a shorter steering stem, but RAISING the bars ill only exacerbate the issue you are having.... you need to get the griping area of the bars CLOSER to the seat, not raise it. What year Sirrus is it? does it have a "gooseneck", a clamp-on type stem? If it's a clamp-on style steering stem then swapping it is easy, and here are several lengths and "rise angles" to choose from... "compact" bars will also move he gripping area rearward., but you will have to remove the tape and levers to swap bars.
