I'm considering buying the z400. I don't have any experience with a liquid cooled quad. What happens when I roll it in the dunes or pack the radiator with mud in the trails? Any comments would be great.

 

Rolling it in the dunes shouldn't be a problem, unless the cap is loose or you bust the radiator, over flow tank or hose. Then, look out for hot coolant[img]i/expressions/face-icon-small-shocked.gif[/img]But, I would think, if that much damage happens, you will have bigger problems to deal with[img]i/expressions/face-icon-small-sad.gif[/img]Mud could be a problem. It would really need to cake up on the radiator[img]i/expressions/face-icon-small-sad.gif[/img] and prevented air from getting through the fins. I guess, the fan would work to cool it down some[img]i/expressions/face-icon-small-smile.gif[/img] If the mud was that bad, I would just watch out for build up and remove the clumps, as you go. We have 3 quads with radiators (one a Z400) and never had a problem with any of them[img]i/expressions/face-icon-small-smile.gif[/img] We're just a little further south then you. And, the only time you really need to worry about mud, is when it's cooler/wet outside[img]i/expressions/face-icon-small-smile.gif[/img] Like this time of year[img]i/expressions/face-icon-small-smile.gif[/img]
