I've been following this one and haven't seen the gas caps mentioned yet.
I have recently painted my tanks and had the gas caps out.
Holy shit, those things are heavy!!!!
If you replace them with the billet ones you will save over a pound up high on the bike.

They (SSR) also have these trick, new push button caps. (I haven't seen them before....)
