Hello from sunny Leicester

Head Gasket sounds a lot friendlier than the valve seals. Would you advise to try the head gasket first, and then do the valve seals if needed or would you do all at the same time? I’ll put a video on youtube later and send the link so you can see what i mean about the chuffing sort of noise. ive never seen it before, but ive only got experience working with 4 cylinders. (ZZR600 and Z400 hardtail chop) so unsure what im listening to with twins.

 

KaptainKwak – im getting quite a shopping list together. You’ll have to let me know what you have and the price.

<p style=”text-align: left;”>Heres the video so you can here the chuffing. Really prominent from 26 seconds in</p>

And a vid showing the oil accumulation under the manifold.

As you sit on the bike, cylinder 1 making the chuff noise, cylinder 2 smoking from manifold with burning oil as the exhaust heats up. Cylinder one seems to put white smoke out the exhaust when revved, seems to coincide with the chuff.

If you have a head gasket blow there will be oil around where the leak is. You need to get the head off. If an engine is run to long like that you can damage the head.

I absolutely agree with Coleighf. A problem like this will not cure itself and the more you use it this way the worse it will get and potentially cause further damage.

Just replacing the head gasket is obviously more straight forward than doing the valve stem seals as well but that is your choice. If it was me I would just replace the head gasket as I strongly feel that will be your problem BUT be aware that if the valve seals do need doing the head will have to come off again. Replacing the valve stem seals is more specialised and the valves need to be removed which does require specialised tooling.

I can supply you with a top end gasket set that covers all gaskets and O rings from the cylinder base gasket upwards but sadly does not include the valve stem seals. I can help you with those as well should you decide to do them.

Another area that could also cause an oil leak in that area is where the rev counter cable fastens to the head. There is an oil seal in there that does leak on occasions. this will tend to leak on the right hand downpipe.

Let me know what you want to do.

That chuffing may be a sticky ,burnt out or bent valve,or even some debris stopping the valve closing properly. But as everyone says you will find out when you take the head off ! Good luck with it anyway.
