Urgent question

I am changing the coolant in my bike and I broke the side drain plug on the engine. It is not leaking now and I have all the coolant drained. Will that hold up with it being broke? Or do I need to get it out?

If I do have to get it out. How do I do it without pulling the engine?Click image for larger version

If it's not leaking let it go.
Otherwise if you want it out you'll have to get an easy out set and be pretty careful not to mess up the threads. I didn't need to use the drain plug when I changed my coolant.

If I was forced to remove that, I would not attempt to drill it without a pilot.

I'm thinking about just leaving it in there and keep checking for leaks. If I do that next time I change the coolant do I have to worry about it then or can I just use the other drains?

I would say that using the bottom drain and the radiator drain is going to get rid of most any coolant you need to. And if that one doesn't leak I would leave it alone.

I'd fill it with liquid alloy,and forget it. More trouble than it's worth.

Since you have a few threads to work with drilling it out might be an easy option.

I have a tool called QuikCenter that would make this a pretty easy procedure.

But you could also make you own. You just need a bolt the same threads as the broken one, and use a drill press to drill through it as centered as you can.

You can now thread this into the few threads you have. If it looks to be square, use it as a guide for a hand drill to pilot drill the broken bolt.

You then have the option to use a screw extractor.

Or you could plug it with something like JB weld and it'd hold forever. I'd make sure it's dry first and clean it out with brake cleaner.
