Oil drain plug on my Ninja is stripped. What can I do?

A friend of mine recently changed the oil in my Ninja ZX-6 and the next morning I noticed a very slow leak. I went to tighten the oil drain plug and after it got just a little tight, it started to get loose again. I'm almost sure it's stripped and it's still leaking a little. I took it to the local bike shop and he said best case scenario it's going to be 150-200 bucks to fix and worst case much more. Is there an easy way to fix this problem?Oil drain plug on my Ninja is stripped. What can I do?
Get a tap and re-thread it to the next larger U.S. fine thread bolt.


Use a heli coil.


Use the drain plugs that self thread for the situation you are in.


Be sure to use a nylon or soft metal crunch washer and **do not over tighten or cross thread again!**Oil drain plug on my Ninja is stripped. What can I do?

u could try to retap the hole. if this works, problem solved. if the original size cant be maintained, u might need to go to the next size larger, run the tap, and use something that will be able to be used as an oil plug.
Why the hell do you have a friend change your oil? If you ride, you should at least know the basics of maintaining your bike. Get yourself a tap set %26amp; redo the drain hole yourself. Almost all the above answers were right on the money. You'd be crazy to pay hundreds of dollars to do this repair!
they do make a kit it is made by heli coil you will have to drill the hole out and put the heli coil in and then the new bolt for the heli coil. i know that your bolt is metric but that will not make a diff. A good auto part store can fix you up and it is the easiest fix i can think of and will work good as new. hope this helps
Most auto part stores sell self tapping over sized drain plugs. Buy one and follow the directions.





I used one on my Ninja 500 and it worked great.





Hope this helps
yes if it is leaking re thread the hole and get a little bigger plug this should cost alot less than 50 dollars compared to your local mechanic
i would go with what has been previously said. it's the easiest way to save 200 bucks that is at the most worth the price of the tap and a bolt to be used for an oil plug, and that still wouldnt come to 200 dollars. ya know, u would save even more cash if u would splurge on getting a service manual for this bike. maybe mr. murphy wouldnt pay u another visit.
Have a Helicoil installed.
I think you have a separate sump plate which can be removed. You will have to take exhaust system off first. It should then be possible to either Helicoil sump or fit a new/used one with good threads.


You could also try Autozone/Pep-Boys or similar for oversize sump plugs, probably Honda civic or Toyota or similar ( Get a metric one)
They have self threading plugs on the market.
