Query approved.

Re: Hero Honda karizma r 2004

Because its gasket is ****ed , screwed , tore , broke.

Re: Hero Honda karizma r 2004

Is it easy to change .?

Re: Hero Honda karizma r 2004

If you`re a pro at engines its a piece of cake.
The gasket lies between the cylinder and the head so all you need to do is detach the head and place the gasket properly and fit the head tightly.
Make sure you use a good quality gasket because the cheap ones break/tear in no time.
The gasket is also called packing in local(desi) language.

Can you attach more images?
Because as i am seeing in the picture the leakage is not from the bore. The oil it has is above the cylinder(bore).

Re: Hero Honda karizma r 2004

Sure ...here are more pictures ,the other side looks clean

Re: Hero Honda karizma r 2004

Bro your head gasket is absolutely fine.
The oil is coming from the cylinder head may be valve cover or something is loose there.

Let me explain what exactly is going on there. There is a chain which is connected from the crankshaft(which is connected with crank to piston ) to camshaft(which move the cams and is responsible for opening the valves)
that chain is sunk in oil from the part which is in the crankshaft area. When it rotates it takes some of the engine oil to the camshaft chamber(a part in head) and that is for lubrication of the camshaft and valve`s actuators and in your case that oil is leaking out the head, now you have to check the valve covers or camshaft chamber`s cover in the head and get them tightened.
hope you understood.

Here in this picture the bolt marked in red circles have to be tightened and the green one looks fine but try tightening it too. These are the bolt which are meant to keep the valve cover tightly closed so that there is no oil leak from the cam chamber.
this should solve the problem.

Re: Hero Honda karizma r 2004

Thankyou so much for the reply brother.!
So the problem is only a loose nut is it .?

Re: Hero Honda karizma r 2004

Take it to showroom for thorough inspection. The reason is, apart from gasket if there anything else needs to be changed, they will be able to tell you.
I would strongly suggest you don' t open the head since there are valves and tappets will need some care while removing.

If you haven't changed the timing chain and chain guide. Do it along with this since it would help to deliver better riding experience.

Use 10w30 semi synthetic oil for better results.

Re: Hero Honda karizma r 2004

The bike was big bored recently bro.!
And yes I am using a 10w 30 oil by shell
