Oil leaking : Urgent diagnostic needed !
eric92;
Bienvenue et comment ca va?
That appears to be a leak from the head gasket. You should wipe all the leaked oil off first. You can try re-torque of the large head studs (remove the top engine mount bracket) to 30 ft-lbs. This may help if the stud acorn nuts have backed off.
To cure the problem, you will likely have to replace the head gasket (means engine removal). How many kms on the engine? Do you get puffs of black smoke out the exhaust? Are you using a lot of oil................dipstick level drops quickly? If the head gasket is gone, you may be sucking oil from the camchain tunnel into the cylinders, and blackening the plugs.
France is very beautiful. I was over there last year for a short trip to Provence and to Normandy................enjoyed it very much.

Hi,
Thanks a lot for your cool response.
I'll try to re-torque it. Just to borrow the material from my neighbor…
I've also bought the engine gaskets (to replace these during the cold winter nights).
The bike is 17000 kms, no black some (yet), not too much oil used but very dirty pavement at every stops
Cool you enjoyed our beautiful country.
Dream to visit Canada in Autumn & winter.

That's a good sign if you are not using much oil. Perhaps the engine does not need to come apart. If the engine has good compression and not using oil, then just keep driving it. Do a good cleaning of the engine in order to see new leaks.
You probably don't want to come to Calgary in the winter..............can be -30 C
. Summer time is beautiful here and good biking into the mountains.

I had a weepy head gasket that I thought for sure I would have to replace. This last time I re-torqued the head I replaced the "used to be hard" rubber washers with the brass ones that Mikes sells. No more weepy head gasket. I'd try that first.

Search several threads about tightening head bolts. Loosen each nut until you hear and feel the big "grank" then ideally remove them completely (buff till shiny) put a little anti seize on the stud then tighten. I have had worse leaks than that stopped after bolt tightening.
Here is a good thread on retorquing.

Tell us how it works for you? We love to know how things that we suggest turn out "in the wild".
I tend to work on 3 or 4 XS650s per year. A head retorque is now part of my "before first fire up" routine. I am sure I will get a leak I can't stop someday but so far I am 100% on no head/base gasket leaks. I'll bet the Honda 750 single cam guys wish they could say that!
