Mysterious Coolant loss? Help
Topped up my reserve coolant in December. Checked the resevoir today and it was empty. Bike isnt overheating when riding or in traffic jams, no visible leaks on the floor after parking. Checked my engine oil and it wasnt milky. the radiator cap is in good condition too. I'm probably gonna head to a workshop to check it out just in case but anyone here faced anything similar before?

Was the radiator still full? When you say you topped up the coolant, what was the level before you did it? Very odd :D
I've had leaks before, but it only needed a few of the hose clips to be nipped up. Only noticed when the fairings were off, it didn't really leak obviously on the floor.

Could be your water pump is shot. If you or a past owner used water, then the impeller could of corroded and torn the seal.
Also, I have Samco hoses on mine and they leak around the fittings to rads and water pump. My NC30 smells like coolant all the time. I thing I'm going to put on some OEM hoses and I just got a new water pump if the one on mine doesn't check out.
You could also look at the 2 cast aluminum fittings on the engine block between the two cylinder banks and under the carbs. A seal could of gone bad.
