Blown headgasket?
07/17/13 at 02:58:10

I have drive few km with my bike now. It ticks on the left side somewhere to the head. Now it comes oil between the head and cylinder. The engine was clean washed from the dealer

My thought is that the gasket is blown and the noise is from that. A blown gasket can sound terribly

I can feel some wind from that area.
Is it possible to remove the head without removing the engine from the frame?
I can get Athena S.p.A gasket set, is that good enough?

Aha, thats the leak over the exhaust. Guess that the oil spills to the left side when bike stands on the side-stand.
But that should not make ticking noise. Could it be the chain anyway? Sometimes the noise disappears but I can't tell yet under what circumstances. And I believe I can feel some drag from the side, no fan in a air-cooler.
The piston bolt? Rocker-shaft? Or what?
My ear locate the ticking to left side, at hight were head goes on.

I would suggest you give the engine a good scrubbing.....then try to find the source of the leak. If you have a blown head gasket.....I believe you may be the first one on this forum. Engines with 8.5:1 compression aren't too hard on head gaskets.

The source of the ticking could be the valve train or some piston noise, not sure about the air movement you feel.

could it be the convection from the fins or maybe oscillation from fin vibration? I get that sometimes too, where I am at a stop and I feel puffs of air against my left leg as I stand on the ground.

Also, when was the last valve adjustment? It sounds like you just got it from the dealer recently.

Reply #7 - 07/17/13 at 09:24:08 There is a minimum lash,, you dont want them too tight. It should be ticking like a sewing machine up there.. I cant remember the specs but I think one of them is around .004", I dont know what your .1 mm is.

Manuals say, 0.08 - 0.13 mm.
I took my camera and went out to record the noise. And there was no noise Sad

It did tick this morning when I ride to the mailbox.
I don't believe in the blown gasket any more.
I have a feeling that the engine has never been opened, looks like factory built except for the cam cover.
Do you open the head bolt a little first and then torque or torque without that?

The proper way to torque the head is labor intensive, and usuallly occurs when the head plug leak is fixed. Two of the head studs are not accessible with the head cover attached, and it takes a lot of work to get the head cover off, cleaned up, resealed and bolted back on.

The cylinder nuts get stuck with the heat cycles and washing and drying and corroding and they can only be torqued properly if you take them off, clean them and apply new anti-sieze....then put them back on and torque them.

I'm use to loosen before redraw. So for me it makes sens to loosen them up first. Have read posts of broken bolts
