    Thanks for your help RJ! I’m slowly but surely getting these ZLs back going. It took me a while to get dedicated to it but it’s on now!

    Thanks for providing the support for our big ZLs

    :hello: No problem glad to help. :notworthy:. Run your bike before doing anything. If the water pump just leaks oil. Then just replace the oil seal. Also check the propeller for play. Put the pump in a vice. Rotate the propeller with your fingers to check for tight spots. Then with both hands one on each side of the shaft & try to wiggle it side to side then up & down to check for play. This checks for bad bearing. Most of the time the bearing closest to the propeller wears out. I have all the OEM water pump part #s listed in this thread for a complete overhaul. I have 12 of each OEM part in stock. I also have the size of the oil seal listed.
