Drain Plug Replacement (Noob)

Hey guys,

Name's Jose and I'm new to not only the forum but also owning a motorcycle. I've managed to get my 78 KZ650c running properly. I recently changed the oil and filter but I just couldn't get the plug to tighten properly. I now have a small oil leak. I looked into my manual and found that the drain plug installed on the bike is clearly aftermarket and much longer. I went ahead and ordered a new magnetic drain plug with the exact thread pitch and length as the stock plug.

Question is, is it possible to replace the plug without actually having to entirely replace the oil? Maybe by leaning the bike over somehow? I have replaced a neutral switch before and leaning the bike worked great but not sure if that would be effective when pulling the drain plug.

Any insight is greatly appreciated.

Just be fast. Not much oil will come out until you actually remove the bolt, and if you have the new bolt ready, you might only lose half a pint. I mean have the new bolt in your right hand ready to go in, as you pull the other bolt out with your left hand. Once you have the new bolt lined up (without being threaded), it will stop most of the flow.

Great! I figured but wanted to run it by someone. I'll give it a shot today.

Thanks!

Hello, jsantana, and WELCOME to KZr!

Would also use a large clean shallow catch pan underneath the bike so that escaping oil may be returned to the engine.

Good Fortune!

I think I would drain it into a clean pan. Then Inspect those threads in the pan, check the fit of the new plug etc. Then worry about re-filling with the oil.

Hey guys! Im back to share my recent success. So turns out the threads on my 650 oil pan were stripped. I could have ordered a new oil pan but I went ahead and gave this silicone gasket stuff a try. I could get the drain plug to tighten ok but just not enough to prevent leaks. I picked up a tube of "VersaChem Super Blue 613" at Oreillys for like $8, and a new 12m gasket/washer.

Super Blue 613

I applied a little between the base of the bolt and the washer then a little more around the top of the washer. I let the silicone sit for about 15 mins as suggested on on the pkg, then I inserted the plug and tightened as far as I could before it would release again. I then let it cure for approx 20 hrs.

I had the obvious concerns of failure but it has been about 8 days of commuting and the silicone has done it's job magnificently. No leaks! It's most definitely not pretty but it works.
