Mysterious Coolant leak

If you own KTM Twin, and you are loosing coolant without any of the symptoms mentioned you owe it to yourself to pull the clutch cover.

Let me elaborate.

2008 SD990
6500 original miles
Loosing coolant every ride... Did not manifest as an issue until ambient temps went over 85 degrees

No coolant in oil
Oil level not increasing
Oil filter not contaminated or disfigured

Moisture and emulsified oil under clutch cover

Culprit.... Water Pump.

Took shop three trips to finally diagnose ( after I told them to pull the clutch cover and look)
Spent $400.00 in transport fees, diagnostics, labour, oil and coolant flush all for naught.

At least now I know how to move forward.

Rebuild the water pump, flush the coolant (again) and do an oil service (again)

Finally get to enjoy the bike I haven't been able to ride all summer.

Suprised that oil/coolant mix only showed up in clutch.

One of (many) first signs of water pump failure is oil/coolant mix being blown out through crankcase breather (also getting past balance shaft seal into generator) into standard airbox, if you have it, or into fresh air or catch can depending on your set up.

If no signs of it there and only in clutch, suggest you check your crankcase breather valve as it may be stuck closed.
