Engine Ice

If you had to would it be alright to add a little water to the radiator to bring the level up after losing some?

Yes, it is OK, but you have to wonder where the missing coolant went, and how much are we talking about. It is best to use distilled water, (no minerals to participate out and be deposited into you're cooling system) and check your protection with a hydrometer after the bike has been run. Also make sure that the overflow tank is full to the cold line with a 50/50 mix, and that the line running to it from the radiator is clear. (under left side cover) If it is pinched where it runs under the front of the fuel tank, it will cause you to loose coolant, possibly other problems....

Radiator cap was loose from me not making sure it was tight after opening it this winter

Read the specs on the Eng Ice bottle. They may not recommend adding any water. I seem to recall this info but at my age I lose my keys often.

Engine Ice is a mixture of Propylene glycol and water,, deionized water. Adding more water water to it will change the freezing and boiling point, but a little will not significantly affect the overall performance. I believe the freezing point of the product is -26 degree F which means it is already more than 60 percent water. Of course you don't want to dilute it too much, but a few ounces to top off the radiator is no problem.

I don't think you should have a 50/50 mix in the over flow, but the same product, Engine Ice, in there instead. You don't want to mix up the 2 different products.

Your're correct gordonv,, you do not want to mix the two, I misspoke when I said 50/50,, hope I didn't cause any confusion robin.
