it is pretty good but it maybe it could use something about where and how to keep your bike when you are not using it. i have learned to not just drop a bike on its side outside because it will usually freeze up. i always keep my bike upright in the winter since i have to park it outside
i never use WD-40 unless i have to and even then i have to go to the store and buy it if i decide to use it. i usually use ATF or used motor oil.
