when you guys say flush is that leaving a hose in to run threw with water or filling it with coolant and warming it, then emptying it out again to refill for the 3rd and final time?
Unhook the inlet hose, stick your garden hose in to it and start the bike.
Let it run for 10 or 15 minutes. Shut the bike off and the water.
Unhook all the hoses to remove all the tap water.
Then hook them back up, fill the radiator with 50/50.
Crank it up, run it up to temp and shut it off, and after it cools a little,
burp the hoses. Squeeze the one on the left side first, then the right side.
Remember: Never add cold water to a HOT engine.
It's ok at running temp but not when its hot.
I used to use Engine ICE but it was a pain in the ass
having to swap fluids out for winter time so now
I just use the 50/50 antifreeze mix year round.
