It will save a lot of time and effort if the oil pump is installed while installing the bore kit (requires cylinder removal).
There are no installation instructions, but if you can replace your piston, you can install this kit. If you don't have any experience working on your engine, we highly recommend purchasing the shop manual for your bike available in our store.
