and remove the modules that you install with make modules_install from 

but take care to not remove the wrong directory!

For the future it may be advisable to use a build-script that builds you 
a package that can be installed using your distributions packaging 
system. In example for a Debian based (apt) system you can use
make-kpkg and in addition of getting a kernel image and modules you get 
a package that can be installed and removed using apt (I am sure that 
there is a comparable tool for any other major distribution as well), so 
your workflow looks like this:

make menuconfig
CONCURRENCY_LEVEL=8 make-kpkg --initrd kernel_image
dpkg -i ../linux-image-<version>_<arch>.deb

this even adds an entry to the boot-loader for you.
and then you can just as easy remove the kernel using:

dpkg -r linux-image-<version>

and the kernel is cleanly removed from your system.
