IVE JUST GOT A GOLD PM SKULL CAP ,I WAS JUST WONDERING ABOUT THE WATER PIPE ON THIS SEEMS TO NOT LET MUCH WATER THROUGH , OR DOES IT OPEN WHEN ITS HOT? COS IT SEEMS TO HAVE SOME THING WITH SPRING INSIDE, COS ON THE NORMAL PLASTIC SKULL CAPS ITS JUST HOLE STRAIGHT THROUGH
make sure the diverter pipe is fitted/not blanked off when running a thermostat and DO NOT rev the engine till the rad is warm or you will blow the oring gasgets.... can pull it out now tbh, its summer, just let the bike warm up befor you ride it
