WE Kitefin mods?

[GCBC]

What are some mods for this thing?
back end feels a little too heavy, id like to take 5grams out of it somehow, replace backspacer with bolt tubes or something...
the ball detent also seems like its not actually a ball bearing, is there an upgrade part to swap to a bearing?
