2003 cr125 bad compression?

I didn't have very good compression on my 125. It also sounded horrible. I changed the top end. i got all new piston, rings, and gaskets. It sounds much better and it's running great, but the compression didn't change that much.. Is this bad? what can i do?the cylinder and everything looked perfect. the only problem is, i can start my bike with my hand. it just doesnt seem normal.

check and see if your rings are sealing properly and check your crank also. get it to the top of the stroke and make sure there is no play pulling it up and down.
