Does anyone know the easiest way to drain a radiator on a 2006 650V2? I want to run a coolant that is supposed to keep the motor cooler in summer, and supposed to be good in winter also. (Liquid performance racing coolant)

 

I might try some "engine ice" or whatever it is called. I think if you just pop off the lower radiator hose that would get most of it.

 

When you do drain it, flush the system a couple of times to be sure to get all of the old junk out of there. I drain the system, fill it with straight water, run it until it cycles a couple of times, and drain it again just to keep from mixing the good stuff with the old stuff. After you get it put in there, let us know how the stuff works. It sounds like that may fit the bill for exactly what I was looking for. Thanks.
