Testing heat exchanger

Going to get the radiators off and clean them through, I’ll then change the oil cooler when I have a bit of time and ordered it and give it a little run and check the system, if there’s no oil in the water I would say that’s the issue !
I had the exact same problem as you. I tested my suspect heat exchanger after removing it by forcing water from a garden hose into one of the coolant ports. It came out the oil port which of course it should not do. It took a while to completely flush both systems, but I don’t see why you’d want to remove the radiator to do it. I wanted the radiator in place to run the engine to properly remove all the contaminated oil. (I bought an OEM heat exchanger on eBay so I could get all the flushing done while waiting for a billet oil to air heat exchanger to arrive from the UK.)

So I Drained the oil and water, changed it all and put it all back together, except for the outlet hose from the oil cooler And ran the engine. Oil was coming out of the cooler from the hose that should have been going into the radiator.

So there’s your problem. Fitted the billet cooler and the bike is back to 100%. Checked all the systems again and all clear
