Hi there and welcome;

It needs a couple of 1" holes in the airbox lid to give better performance as well.

As for the swingarm I'd think they'll be discontined by now, but someone will have one lying around, put an add in classified.

I've never even heard of an oil pump breaking.

Stock jetting is here.

R6k's have adjustable suspension F&R, magteks wheels and a dry clutch.
