Hi folks, I've finally got my ty registered and am now able to use it. Since I have been using it I have been wondering why there is no guard of any sort over the linkages to stop mud and grit getting into the bearings. I know there is not a lot of room but I am thinking a bit of inner tube or the like would be just possible to be squeezed in there. I am new to trials. So is there an obvious reason why not, does it not cause any broblems or what do others do?
