Hello all, **DISCLAIMER** I know nothing about KTMs, and I'm not that great of a mechanic. ** I'm trying to figure out where a coolant leak may be coming from. When you start the bike, there is no leak. As the bike warms up, the radiator on the shifter side heats up, the one on the brake side does not. I imagine there is a thermostat in there somewhere. Finally, once the bike (and the left side radiator) gets hot, suddenly coolant starts leaking from somewhere on the bottom of the radiator(s) directly onto the head pipe. Tons and tons of white smoke coming off the pipe. Is there a thermostat down there that opens up or something that would cross over to the other radiator? What could be leaking down there only when the bike gets hot? Thanks.
