K 75 do I fill the radiator to the top of the cap?
« on: June 25, 2016, 10:33:28 AM »
I would like to know in how much water/coolant (I do not need the mixture ratio) to put inside of the radiator?

I have done a flush and cleaning on the radiator and now I want to know how much liquid to put into the radiator because I can not see until it starts to coming up to the cap.

Thanks anyone.

fill it up to the top of the filler neck, then burp it by squeezing the big hose running through the crank cover until bubbles stop coming out.  keep an eye on the reservoir the first couple rides and top up if necessary.
