I just bought a this 2017 Z125 off of Craigslist. The bike only has 94 miles on. The previous owner lost interest and sold it after sitting for 2 plus years.
I decide to do an oil change on it to swap out the old oil. I reach down to undo the drain plug and it didn’t take much force to loosen it. Along with oil dripping into my hand, metal shavings and the drain plug fall into my hand.
I tried to screw the plug back in but oil kept leaking out. Attached is what the drain plug looks like currently and it is super loose.
I am trying to figure out what my options are to repair this? Is there enough threads in the case I can retap the hole? Or is my better bet pulling the engine and having the drain rewelded? Or do I need to get a whole new crankcase.
Please let me know if anyone has experience with this or their suggestions.
