Oil leak! What do I need to do? 1981 CB650

[anthonyandminnie]

I have an oil leak and need to do some work . I've never done an engine repair before so not sure how and what to do.

I've got a complete gasket kit which I bought from Japan. I wasn't sure what the real problem is so bought a complete kit.

Is there a YouTube video or step by step guide to a gasket change? I might add well do a complete gasket change.

Here are some photos of the problem. The white powder is just to determine where the leak could be.

I am guessing head gasket.does it run? Ifits head gasket you must remove the head,looisen all the top end,then replace all oil seals,usualy they are the culprit for leaks,not the head gasket.You have to get it in time to run,etc.Not easy, but doable.

Most likely cause is one or more of the 6 rubber pucks that cover the cylinder head bolts. Check number 13 on this link. It should be part of your complete gasket kit.

Thanks for the replies. Do I need to remove the tank? Looks like it's difficult to remove the head.

Welcome here!

If you have oil above the header pipes level I agree that rubber pucks are suspicious.
In this case you should find the first and most important information here:

But don't hesitate to use the forum search for further info.
As a beginner, you should spend some time on reading here and in particular in the manual. May take hours, but no problem. It is good to know what you will face before you remove the first bolt. And if you start working, spend time on cleaning parts. Again hours do not count here.

Please believe these head cover threads are really susceptible, there is no need to find it out the hard way yourself.
Not much better with the head and head bolts btw.

Good luck!
