Small oil leak on cooling fins

[rynr]

You have to disassembly head covers, clean the engine fins as much as you can. Then star t the engine, heat it up and look where it's leaking. If it's clean go for a ride and stop after a few killometers and look for changes - you can obviously ride without chrome head covers.

If you have almost whole cylinder covered with oil, you and we are not able to see where it's leaking. Sometimes oil comes higher than it leaks in the first place because GZ can provide better acceleration than gravity

If you replaced the gaskets, check valve covers and this cover that's taken off in third picture in my previous post. You can replace o-rings under valve covers anyway, cause they're cheap and it doesn't need much time to replace them.

There is a screw and nut hanging upside down in the middle of the block at the front, it seems to be covered in oil. Any clues? Maybe time to bring it into the shop

That 'screw and nut' you seem to be speaking of is really a
cylinder head bolt. Some have mentioned that theirs is loose or missing.
Put on a nut, if yours is missing.
Torque it to 7 ft-lbs.
Hopefully that will take care of it, but if not I'd suspect a new
cylinder head gasket might be in order. Yes, you can do it yourself.
Between the manual, and an excellent write-up elsewhere in these forums,
I just did it and can offer some good tips, as can others here.
The gasket cost me just under $30 (WW - how much is that in metric? )
and make sure you use a good sealer; I used Hylomar, just under $10.

Alantf strikes again. Good one.

Cylinder head bolts torque should be around 8-12 Nm, but it may not help even if torque is right.

Guys! Do bolts (they hold cylinder halves together, see pictures from the past i post) which are on the top of the cylinder, behind the cosmetic chrome cover, have a gasket or i don't know how to say it, the thing, o-ring... to prevent oil leak? If so, does anybody know if it commonly used or you need original from suzuki?

Thanks!

Uh, what???
First thing you do, is look at the manual and then the parts list, and
find out what you are talking about.
There are no 'halves' to the cyl head cover, cyl head, or cylinder.
If you are asking about between the cyl head cover and the cyl head,
no gasket, just a sealer.
If you mean between the cyl head and cylinder, yes, there is a gasket.
But there is no sense confusing you if we are talking about different things.
I'd like to help, but first I have to know what I am helping with.

Nevermind! I hae checked and the pics i posted weren't the best ones. I saw that Rynr posted his pics and i beliee I have the same problem, like he did with the 125. It's propably a leak from tachometer, as he said, cause in my case it's very similar oil leak (the oil being colected around one of those screws), see page 2.
Sorry Old for my bad english.
Thanks and take care.

I think i'll have fun watching my mechanic at work...

Can you clarify what you mean by tachometer. I think you've used the wrong word. A tachometer is a rev counter, which the GZ doesn't have.
