I had an unpleasant surprise last night, I noticed my bike had starting leaking coolant and it was puddling below the bike. I figured I could ride home and see what's up so I poured the contents of my water bottle to the the coolant tank. After a few kilometres though the engine started heating up unusually high and the tank was almost empty so I had my friend pick me up in his van and take me and the bike home.

Well, today I stripped the fairings and this is what I found:

It was dripping of the circled bolt, there's some marks of it running down the cylinder too although I didn't see a leak anywhere else. I just idled the bike though so those might have come yesterday, I was riding it properly before I noticed the problem. Anyone know what's up with this?

 

Just tighten that bolt up, no need to worry about it; that is one of your drain bolts for your coolant. That one is for the engine block and the other one is located on the water pump housing.

 

I took it out to check if the grooves were busted but it looked all right, no coolant came out though. That's because it only circulates when the engine is running, right? I put it back in as tight as I dared and idled the bike and it still leaked. It should probably be done with a torque wrench, anyone know the specific torque for it?

 

Once you remove that bolt, you need to add sealant to it again. It wont seal on just the threads alone.
