Leaks: Oil, water and clutch?

Leaks: Oil, water and clutch?

Just got back from 150+ mile ride. Bike is dripping oil and water. Clutch slave looks oily. Oil all around the oil filler cap.

Before the ride the oil level was between top and 2nd marks. After the ride the oil level is down to 4th mark from the top. Coolant overflow was between min and max, now way below the min and almost no coolant in the bottom. Level not even visible on the bottle.

No indication of over temp, overheating, low oil pressure. No unusual behavior or noises. No smoke.

It’s all on the left side. Oil and water leaks appear to originate at or near the top of the radiator and/or above valve covers. Saw a water or oil mist just after shutting down. Looks like it has been dripping down on upper radiator hose, horn and left engine case. Top right corner of radiator (when viewed from the front) appears to be wet. I have a radiator guard and never do wheelies.

Any ideas what happened and what needs to be fixed? Did search, but didn’t find the exact same issues. Taking it to dealer tomorrow. Hoping it’s not major and covered under extended warranty. Hope no engine damage. Thanks in advance!ImageImageImageImageImageImageImageImage

Looks like the radiator might have failed on a seam or been damaged somehow.
Oil on the clutch slave could just be chain fling.

Oil traces on the engine, might be a leaking cam cover gasket.
Oil traces around the filler pipe, could just have been oil that was spilt on the last service.
Lower oil level on the sight...how consistent is that anyway?

I would say that you just have a radiator issue, and your engine could do with a deep clean.
