Honda OEM valve cover O-ring for Monkey 125
Another cheaply priced Honda OEM part through Webike is the valve cover O-ring. I have recently been opening up the valve covers a lot due to engine upgrades and following that up with maintenance checking the valve clearances so I ended up developing an oil weep from the lower valve cover. Nothing serious but it is always nice to have zero oil leaks to keep a clean engine. Was time for a new O-ring so cleaned up both mating surfaces, applied some engine oil to the O-ring and torque the cover down to the OEM specification for leak free installation.
