I used Honda LL auto coolant at the first coolant change
and have used Prestone LL yellow jug twice for coolant changes.
Still riding with the OEM pump!
I skipped 24k change. Oops..
52,542 2/13/08 coolant Honda LL5Y/60K miles.
I've been using Honda coolant since my bike was new. It's a bit pricey, I ordered a few quarts to last me a long time online a few years ago to get the best price. You can Google to see who has the best prices.
