No, it's not drop-in. But the instructions are excellent. There's a little grinding, some soldering, and some flywheel cage dis/assembly. But it's all doable. You might need some help from your elders, but it's definitely doable.

I'm serious, it's one of the best mods I've ever done. Scope it out.
