Some (not much) play is normal, but if you have a too-hard aftermarket sprocket you could end up with this:
If your splines are straight you're good, but I recommend running only OEM front sprockets.
I have be running aftermarket fronts on my XL500 since 1979 with no ill effects, but as you can see in the pic, my XR600 was not so lucky.
I will buy no more aftermarket front sprockets.
Edit: I see you have the finer spline. I don't know whether play of any amount is normal on that model, but still, any damage should plainly show. And, I would still use only OEM sprockets.
