Well I just picked up an 01 929 last Friday. So I'm new to forum. I have one quick question that I couldn't find through searching. I am going to do a coolant flush on the bike since the coolant looks a little off color and I was wondering if anyone uses Prestone (or other major brands) flushes to do this on the bike. I have used the Prestone flush in the past on cars without problems. I did order 4 quarts of the HP premix coolant from Ron Ayers, so I won't be putting Prestone coolant in. Should I use a Prestone flush that can be picked up Auto Zone or something else?
