this isn't my engine
i have some sort of a leak , i think its coming from the circle area , but is always leaking down were i have put the red mark , can anyone shed any light on this please?

The circle area is a coolant transfer pipe, if that fails they are not available new but you would leak coolant not oil.

There isnt anything there i can think of that would or should leak.

Perhaps it is coming from the top of the rockerbox and working its way down?

its coming out a green colour and smelling like oil and petrol ?? iv i take the take off will i get a better view of whats going on?
but every day were the red mark is , is were im getting this fuild leaking

Green colour? This sounds like the coolant you put into the engine...

The oil and petrol smell isnt too good unless the head-gasket has gone and there mixing in the combustion cycle.

Some others will have thoughts on this..

thanks neo, ill get the tank off and have a better look when i get time and then ill update,

If that's really where it's coming from, the obvious thing is that the coolant hose isn't tightened on tight enough.

Other than that, there must be some type of seal between the elbow joint and the transfer pipe. Probably ust an o-ring. That might have given up. If you are lucky it'll be a "normal" metric o-ring. If it's a Honda-only job you'll have fun finding the part number?

there are four o-rings.. one metric round one on each end of that chromed pipe and one werid honda jobbie each side under the L shaped piece the pipe goes into

If one has gone then the others won't be far behind, and will probably break when you disassemble to replace the one that is broken. Might as well do all of them.

ps - Looks like you've lucked out and found the only man on the internet who has a clue about nc24's!

I gave it a good clean round the engine so should have a clean view of were the true leak is coming from , do you think when I flushed the water system out I might have up set some think ?

Unless one of your hoses is loose.

I've only seen the middle pipe fail once and I had to fabricate my own replacement as new ones are not available.

You really do need to track down the leak properly to its exact location and we can go from there.. if it was coolant it sohuldnt be petrol / oily unless there was hg problems.

probably running down from the rocker-box.

Spray some de-greaser / engine cleaner in there and dry everything off fully.

run the bike witohut the panels on and use a flashlight to isolate the leak.. let me know where its coming from and we can find a fix for it!
