GS1000 Timing chain tunnel leak

[Reinhoud]

Gents,

 

My bike is in parts, I've got a lot of oil leaking all over the cylinders, the front. 

I think it's the head gasket, I got new gaskets in the other day.

 

It's a GS1000 with 78.25mm pistons, so I need Cometic gaskets.

The stock square O-ring doesn't seem to do much.

 

Before I start to try all kinds of stuff (make a mess with liquid gasket) are there tips or tricks to prevent if from leaking again?

 

Thanks

I would check the 2 inner head bolt Orings first.

I don't think you need any any O rings with the Cometic gasket

Lots of oii is generally the valve cover gasket

It's in the center, not at the ends.

Check the oil seal on the revcounter drive. I had it leak on mine and oil ran down the centre of the engine.

I didn't say they were on the ends?

Oh, didn't read that properly..

 

Inner headbolt O-rings?

I don't have the tacho drive in anymore
