Was changing my oil the other day on street 500 was the first time I changed it and the oil plug was on pretty tight I got it off o-ring still attached and I tried to reuse but it won't tighten completely do I need a new o-ring or a new oil pan ?

Always replace the o-ring when changing your oil. I don't know about other bikes, but that's pretty much SOP with all Harleys.

Thanks man was my first oil change on a real bike ever I'm going to try and get a new oil plug and o ring hopefully that works but if it doesn't do you know how much it is for a new oil pan replacement

I have no idea what an oil pan would cost. There may be other options, though.

When you say "it won't tighten completely" do you mean that the plug stops turning without sealing, or do you mean that it never stops turning? If it goes finger tight and still leaks you probably just need to replace the O-ring. If it doesn't stop turning you have stripped the threads.

Stripped threads on oil drain plugs are common enough that oversized, self-tapping plugs are available to cut new threads. That's a pretty common solution.

Stepping it up a bit your auto supply store probably has helicoil or solid inserts for thread repairs.
