Hey everyone this is my first post here so here it goes. I just bought a 97 kat 600 with 14,000 miles for cheap. Im trying to fix it up slowly and I havnt gotten a chance to take the fairings off yet, but I have a oil leak and it only leaks when its running. I noticed it comes from the front of the lower fairings some where, so I was just wondering what I should look for that would make it leak only when its running. Im not sure what work the bike had or anything so I figure I have enough time to get her goin before ohio summer sets in. Any help is much appreciated.

Pull fairings , hoes down with something (I like brake cleaner or Purple Muscle) , then see for SURE where it leaks from . Could be from a few places , really . Cylinder head cover , oil lines , head gasket , side cover .... best bet is to clean it first and locate the leak .

Uh oh. Check that oil plug. The Oil pan might be stripped completely or partially and the guy left it for you to fix. I would not ride her at all until you get it resolved. All it takes is for a little oil to hit that tire and you will become an airborne ranger in the worst way.

Mine is out of service right now as I wait to replace my oil pan due to me stripping it like a bonehead. It is easy to do and only takes a little pressure. When you change your oil again, get a fumoto drain valve and never worry about it again!

I don't think its the oil plug. ShownLow states that it appears to be coming from the upper front of the engine. With the miles on the bike(kinda low for a 10 year old bike) it might have sat for a time. I'd guess its the head gasket since they usually get leaky if the bike sits. My brothers 96 GSX750F had the same issue when he got it two years ago with 14,400 miles on the ticker.
Washing the engine and then letting the bike run for awhile should clear up where its coming from.

i'm voting for oil line or valve cover - not head....again -like everyone else said - clean it and see where its coming from - hell - might be as simple as a loose clamp

Thank's for all the replies so far makes me feel welcome!! Anyways I checked it out and it appears that (I dont know its called) a bolt just below the valve cover and on the top of the head on the left side (shifter) has a leak its on the top left. Looks like a pain in the arse cause 1/4 of it is behind the frame. I cleaned it all up and the washer looks smaller then the other ones and I do see a small gap where its coming out of. Im guessing Im gonna have to unbolt the motor and try to move it back like half inch to get to it. Anyone have this happen or did I just confuse you lol.

On the top, or on the side of the motor? I think a picture will get you a much better answer.

It's on the side but at the top right below the valve cover so if your looking at the left side of the motor its at the top left right below the valve cover. I might be able to gete a pic tomorrow with my gf's camera phone. Like 1/4 of the bolt is covered by the frame its a really big allen wrench that fits it. Id say about 10 inch's to the left of the gas petcock.

Pretend this pic is of the other side of the motor... can you circle the spot the oil is coming from?

Sounds like an oil gallery plug.

number 28

Is that where yours is leaking?

the 'gasket' is #29 [$0.70], but the plug may just be loose.

I think you will have to rotate the engine cradle down to get at it.... not a big deal. Some one will go into more detail if this is what you need to do :]

Almost forgot I looked at the other bolts and the one that is leaking seems to have a smaller washer then the rest like its not flush all the way around.

You may find that it does not have a washer at all, when I first looked at those plugs when I took the engine out of my bike, I thought there was two washers on each, but there is only one. :dunno: I will try to explain how to lower the engine to get at it, but there are people here who are much better at describing things than I am....... hint hint ;}

My questions would be why is that bolt leaking (why has anyone touched it since the bike left the factory?), and are you 110% sure it's not from the valve cover gasket directly above that spot (which is prone to leaking if the gasket isn't in the track of the mating surfaces just right)?

Oil oil everywhere, not a drop to leak.

Well I sprayed some carb and choke cleaner on the motor to clean it off. Then I started it up let it run seen the oil dripping down the head checked it once to make sure it wasnt the valve cover gasket then checked it again and Im 100% positive that it was coming from the bottom of that bolt where the biggest gap in the washer is. It looks like theres a smaller washer on it cause its flush at the top of the bolt but when I look at the bottom I see a gap not a big gap but there is a gap. That gap is where the oil is coming out of.Right above the bolt is clean as can be all the way around.

I'm with marc on this one... are you sure it isn't a bad valve cover gasket? Those little rubber half circles are part of the gasket....

Im positive it's coming from the bolt theres a gap in the bottom of the washer that's on it and I can see it coming from under it. The gasket looks good everything above the bolt is 100% clean, but under that's a different story.

It's a washer or a gasket? Ron Ayers fiche shows that to be a rubber gasket. #09168-14004

It should be a copper crush washer. The same type as on your brake lines. Just go to a hardware store and match them up. No need to go to a cycle shop or order the things.

How do you figure? The fiche doesn't show a crush washer on there at all.

Item 29 is a rubber gasket washer.
Current part number for it is 09168-14004.

I'd pop by your local dealer and order two (it should take them under a week to get it). Meanwhile, you can investigate how to remove the lower frame and rotate the engine down a bit. With the fairings off, this could easily be an under 2-hour job.

IMHO: consider replacing the front rubber isolation mounts while you're at it. It'll make the bike much smoother.

good call - any time you unbolt a major part (like motor, subframe, etc) is a prime opportunity to take care of those little periodic maintenance things.

ie - I did brakes and fork seals at the same time....plus painted the forks.....Always knock out what you can at the time.

That's what I was thinking to, Check everything out then double check it make sure everything's tight etc.... I can already see one of the overflow hoses needs replaced from under the tank. It started to split where it meet's the tank. Talk about a fire hazard.

The CyberPoet
01-17-2007, 07:51 PM
Actually that overflow hose is primarily for rain water that gets into the cap area, but yes, it could easily be a fire hazard if you spill fuel.
My suggestion: Always replace drain hoses with colored hose. Makes routing it back when you reassemble the tank/fairings after working on the bike that much easier (less likely to confuse which hose was which). CycleGear and many other stores carry colored versions of that hose.
