Oil/Coolant Leaks

So a while ago I had a small spill:

After that spill, I started to notice pools of liquid beneath my bike when I stopped... turns out coolant leak.

So today I topped off my coolant reservoir, started up the bike, and there is one (coolant) leak at this bolt:


Here's a different view with no arrow (bolt that is black and not covered in salt is the one I'm talking about):


Left side view to help give some perspective: http://i.imgur.com/Ft5XIZE.jpg


On the right side I noticed two leaks:

In this general area: http://i.imgur.com/5EtZsj7.jpg

The bolt diagonally down to the right seemed to be leaking oil, which would drip down the exhaust pipe and below.

There was a coolant leak further to the right of this picture that I couldn't pinpoint its exact location yet...

Once I saw the oil leak I shut off the bike.


Ideas on how I should fix this/what should I do would be much appreciated...

I would like to avoid paying $600+ to have a mechanic look at it...

First thing you can do is take the bottom fairing off, clean the leak areas really thoroughly, then see if you can put baby powder or something similar that will stick ok to the areas where you're noticing the leaks. You could probably get a couple more ideas for this by googling how to find leaks in an engine

You need to pinpoint the exact locations of the leaks.

During that fall, there's a good chance a part or parts of the engine suffered cracks, if that's the case then there's not much you can do outside of buying a new engine. I know that's not news you want to hear, and maybe that won't end up being the case. But objective number one needs to be to pinpoint the leaks.

Depending on the age of your bike, you may need to replace the coolant pipe o-ring and gasket, then properly torque all the bolts. The clutch side may require a gasket and also properly torqued bolts. Also do as recommended, locate/isolate the leaks and inspect for possible engine crankcase cracks.
