Check your swingarm drain holes.
So, I had some issues with a tight chain adjustment bolt so while putting on the summer tires I decided to pull out the left bolt and have a look. What came out of the swingarm was about a litre of water. A further look found a stone in the drain hole and a lot of crap piled up behind it.
A quick clean and re tap of the hole and all is well now.
Just a heads up.
Falling down is your bodies way of saying you just screwed up.
