I have a 2017 KTM RC 390 race bike. I have removed the coolant thermostat and the bike has 2019 radiator and fan. The bike runs great without any issues.
The coolant is disappearing from the coolant reservoir and I cannot identify the exact issue. I drained the coolant, checked with vacuum radiator filler for any leaks, and refilled it. There were no leaks in the coolant system there was coolant in the engine. The vacuum refiller only refilled the radiator partially and had to put a little coolant manually (not sure if this is normal).
The engine oil color seems normal. In case you have pictures of engine oil mixed with coolant, I would be grateful if you could share them. I plan to change the water pump seals anyway, as I am not sure what else it could be. Could it be that the coolant is leaking for the reservoir overflow tube?
I am also wondering if it could be due to some underlying engine issues. I am worried that if it may be blown head gasket, but based on what I read it seems like blow head gasket is supposed to increase the coolant level in the reservoir.
I would be grateful for any help!
