hello friends, I have a WR250 2 stroke, running fine but the gasoline tank (plastic, 96 model) has been cracking at the top right side, just where the screw that holds the plastic radiator cover goes in (top one). Any suggestions on how to repair this crack? I have tried several brands of epoxi type glues, always cleaning well and preparing (sanding) the surface... nothing seems to hold, all of my repair attempts have failed.
