Water inside swingarm

Hi

This summer we had plenty of rain in Sweden and I suppose there has been some rain in the USA too?

When driving in rain it's accumulating water inside the swing (at least on the left side)

There is a drain hole on the left side (on the underside of the swing between the bobbin hold and the rear axis nut). This hole is always sealed with dirt, you will have to clean the hole with a nail and then you will see the V "pee" probably up to 50 cl of water.

Why is there no hole on the right side ? It must be accumulating water there too.

How about rust?

Here is another thread on this subject (Versys UK-forum)

Good point, CPHB. I saw that thread before, and we did get a lot of rain until recently here. I'll have to check mine too. I haven't ridden in the rain much, but have crossed a couple creeks, and also washed it a few times.
By the way, upon removing my rear swingarm to inspect and grease its needle bearings, I found that the swingarm's inner bearing bushing (inner bearing race) was nearly seized tight (no rust or oxydation) in the needle bearings, and wearing in on the mount bolt and within the frame already at only 2600 miles on the Versys. The inner bushing is supposed to stay put with the mount bolt in the frame, with the needle bearings rotating around it with the swingarm... I smoothed down the bushing with wet 1500 grit silicon-carbide waterproof sandpaper, then polishing compound, wiped it all clean and re-packed with synthetic grease. The bushing fits a bit loosely within the frame which has to be torqued down on it, so I secured it back at 90 ft-lbs instead of 80. It's rotating nice and smoothly now, and I don't get that strange feedback in sharps bumps like I used to.

The gull-wing swingarm on the right side is aluminum, it won't rust so thats why there is no hole there.

Left side also appears to be aluminum, or at least its not steel anyway. I tested it with a magnet, it didn't stick so its not steel No worries about either side rusting I guess.

LOL! It's an all aluminum swingarm. Aluminum does oxidize. The outside is protected by primer and paint, but I'm not sure about all the way inside it.

Yes aluminum does oxidize but does not rust. Unlike rust which flakes off, aluminum oxide hardens on the aluminum forming a protective barrier against further oxidation.
