On my 2 stroke engine while taking a look at the cylinder ive got maybe a centimeter long scratch on the inside of the cylinder. I can just get my fingernail inside of it and im wondering if i should get it replaced.
Scratched piston replacement?

Unless you have a noticeable reduction in compression, you should be OK. Also, if it's outside the combustion chamber, forget about it.
What made you look anyway? Rings OK? If it's new damage, you should make sure the case is clear of debris.

Unless it is such a deep gouge that you you can trim your fingernails on it I would not worry about it. Small scratches are not desirable but unfortunately all too common in these engines. They are usually caused by manufacturing debris left inside the engine by the factory. Final inspection/ quality control is still somewhat a mystery to them.
Enjoy riding the engine until she blows, then rebuild it or replace it.
