Oil leak/ complete oil dump

So i checked the bike over after the winter and it all looked ok.

Started it up and It just decided to dump it's oil out after i started it,

Noticed it and shut it off but was running fine at the time, ran for maybe 10 seconds before i noticed it.

Then just continued to drain out till for quite a while.

The sand underneath was to soak the oil up to make it easier to clean up.

Not taken the fairing off and looked yet but from what i could see at the time all the oil was running off the oil filter, but i gues that's just because it's one of the lower points on the bike.

Needed an oil change anyway lol, just hope it's nothing major and i can find where it's coming from.

I guess I don't understand how it could be anything good?

First things that come to mind are:

Loose oil filter (like, REAL loose)?
Oil plug?
Oil pipe banjo bolts came out?
Cracked oil pan?
Hole in crankcase?

Not sure as it was fine when put away before xmas and just emptied itself after being started up. It's not coming from the oil drain plug, and not running down it either,
I'm assuming that something has given under pressure, so hopefully just something simple as pipe to oil cooler? or filter itself has somehow given out?
It seemed to be running from the bottom of the filter.

Once i've cleaned the oil off the floor i'll put it on paddock stands and remove the fairing to get a better look and update then.

Pull the filter and look for a split seam. Hopefully you didn't have straight water in it over the winter and crack the head or block.

Could also just be the seal on the filter.

What about the access nut for accessing the end of the crankshaft?
It has a rubber seal on it and if it comes unscrewed you will loose your oil like that. Remove the fairings and have a look.

I'll remember that Dave. Thanks. One thing I learned about working on bikes is if I don't know what it is, or what it does, I don't touch it! There is an oil plug on my Yamaha that just looks like it wants to be unscrewed. Many have unscrewed it, and regretted it.

It's not another K&N filter is it?

Loads of them bursting leaks from that stupid welded nut.

Hm. Seems a bit serious. As others have said, check your filter for cracks or a dry seal. Check your pan for a break in the gasket. Examine the whole bike. Not familiar with the engine on your bike. Is it water cooled? If so, check your coolant for oil…

Sounds to me like something froze over the winter and let go.
