Ok, bikes out for paint and I've been tinkering around to include my KG install and Thermostat housing. Drained most of the coolant out of the bike. Refilled today and good news is there are no leaks. Bad news is that half of the KG looks green and half of it looks orange. Did I need to flush the system before adding the HD coolant? I thought it was all the same coolant? Am I trippin or is the stock coolant different? Whats the easiest way to flush the system if needed? Can I used regular water to flush and what's the quickest and easiest way? :banghead:
