Need help, want to ride...please

I have been off my bike for almost 3 years now due to military requirements. Finally did a ground up rebuild and powdered everything that was silver gloss black..I'll post pics eventually. Anyway, 96 vfr750. Replaced all sprockets and chain. Front sprocket I dropped to a 15 tooth (sunstar). The issue I am having is that when the bolt is torqued to spec (yeah, that kind of guy) there seems to be a little end play, the sprocket is not tight to the output shaft of the transmission. I tried another manufacturer for the sprocket with the exact same results. I cannot find my OEM sprocket to compare to and it's been too long to remember. The OEM manual does not give specs. IS THIS NORMAL?

Thanks in advance,

Sleeepy.
