Hi guys, I am a newbie here and I need help with my XJR1300.
Two seasons had no problems with bike, but today - oil leak from the left side of the engine.
See photos.
I have cleaned the engine and left it to dry.
Then I ride on bike 1 hour and I could not see anything leaking.
But in several days I had ride again and found the same problem with leaking.
And at low speed, the engine began to twitch and then stops.
Thanks for any advice.

Ok a few questions about this please.

 

- Are there any signs of leaking on the back of the oil cooler, or from the rocker cover gasket at the front?

 

I'm trying to see if its coming from somewhere other than the head stud it is pictured on.

 

- Was the bike on its side or main stand while laid up for a few days after cleaning?

 

That's the left side of the barrel pictured and the bike would be leaning that way if on side stand.

 

- You say is coughed and stopped, was there any blue smoke from the exhaust when started at any point?

 

Looking to see if its burning oil

 

- Have you had any work done in the last few months on the bike?

 

Cheers,

 

Dave.

Hi and thanks for the questions/answer.

- Are there any signs of leaking on the back of the oil cooler, or from the rocker cover gasket at the front?

No, there everything is clean, no leaking. Engine absolutely clean. Only in front and deep inside on head stud (as on pics.) 
 
 

- Was the bike on its side or main stand while laid up for a few days after cleaning?

Yes, bike was on side stand.

 

That's the left side of the barrel pictured and the bike would be leaning that way if on side stand.

Yes, it is left side.

 

- You say is coughed and stopped, was there any blue smoke from the exhaust when started at any point?

Sorry, I  did nit see it. Actually not. 

 

Looking to see if its burning oil

No. Temperature normal. No overheat.

 

- Have you had any work done in the last few months on the bike?

With engine no. Month ago only carburetor cleaning. Removed the second left float chamber for cleaning.

 

Cheers,

 

Dave.

Hello again and thanks for the extra info.

 

So as far as I can think there are two possibilities here;

 

1. When the bike is warm after use and you put it away it sits leaning towards the left. If possible can you lift your fuel tank off and look for any oil leaking from the valve cover gasket, specifically pooling around the top of that stud? Any oil sat on the copper washer could slowly wick through and run down the stud as the bike cools and everything contracts.

You would struggle to see a small leak in this area with the tank fitted, the tank should only be removed when the bike is fully cold as fuel leaks from the carb pipework onto the engine and could start a fire.

Look carefully for any small signs of a leak.

 

2. Oil drains from the valve train via the front cam chain area. The slight forward lean of the engine in the frame facilitates this and is the only way that oil can return to the sump from here (unless you're doing a wheelie!) The head gasket forms the seal between the barrel and the head and is bolted in this area by two through bolts, it also doubles as the mount point for the oil cooler hoses. Check carefully for leaks in this area as it looks like oil is tracking from towards the centre outwards in the first picture you posted.

 

If the bike is on its side stand then it could dribble along the cooling fins over time, the fins themselves are quite rough in some areas and can hide stuff easily....

 

There is a third ish possibility.....

 

Head gasket failure   :angry3: But this is unlikely IMO as there's no other warning signs of that from your description.

 

Hope this helps,

 

Dave.

 

Ps. Any idea why it cut out on you, or are you saying that was unrelated?
