Coolant loss

Speed Triple 2010
Checking my bike for the week ahead as she was running hot on the way home from work on Friday.
The coolant was very low, in fact I reckon I put in over a litre. (remains from a bottle plus most of a new one)
When I checked it two weeks ago, the overflow/expansion tank was fine.

If I have lost that much so quickly, would it have been a one off thing such as overflowing from the pipe while driving and I didn't notice!
The oil appears fine from what I can tell on the stick, no sticky mess or odd smell and at the level I would expect.

No smoke from the exhaust other than until the exhaust warms up
No loss of power

What should I be looking out for, other than the coolant level!
One thing I understand it could be is it may be leaking into the exhaust port from a blown gasket, so maybe a pressure test is in order.

Any further advice?

 

Hi guys,
Cap was new earlier this year, but doesn't mean it could be faulty now.
Just keeping an eye on it and if it happens again or level consistently drops then more investigation will be needed.

 

Got to work this morning and my right boot was wet, the other one was dry.
So got home this evening and took the right side guard off the radiator, took my tools to the bleed screw and the exit hose in the top right corner and it took a couple of twists, so maybe that was it.

The expansion tank was empty again so I filled it up and will check the radiator itself tomorrow afternoon.

Hopefully that cures it, otherwise it may be a new radiator :/

Evilbay and Chinese come to mind, but I have heard they are made of cheese! - 'Delboys Garage' has used them before with success.

 

These are Samco hoses I put in the Spring this year,. Seems the jubilee clip thingy had just worked loose.

 

Still leaking..although other than the loss of coolant from the expansion tank the radiator was right to the top this morning.
Will do more testing over the weekend, have it running and see where it is coming from.

Oooh, I can use the thermal camera on my Cat S60 phone, at alast a genuine reason for having it
