My old KTM 500MX would really beat the sp rocket bolts up, they were visibly worn at at each change, and wore out the holes so there was a lot of slop. I reamed the holes to the next bigger size, and made sure every thing fit tight. A rear hub for an oldbKTM dirt bike was about $500, so I didn't want to break the ears off it, that's why some people change them out every time. My 950 uses that strange pin setup, and 2 places told me not to replace the screw that go into the pins if they are not damaged.

If your sprocket rides directly on the screws, some do, some don't, I'd change them, they are cheap insurance.
