should valves be oily?
Hi

I opened the valve cover on the xt600 and see oil on top of the valve and the adjustment screw is a bit oily too. Is this normal? I woul think that this thing should be dry?

I took a picture but cant post it yet..

Also the screw on the left side of the crankcase under the cover, the one you turn around anticlockwise to find tdc, it was a couple drops oil in there too..

Things would wear out pretty quickly if there was no oil up top. If you think how quickly those valve rockers and the cam is moving when your reving the engine they need some lubrication. When you take the small covers off to get at the flywheel nut, to rotate the engine, and the one to check the timing marks then there should be a little bit of oil coming out of there too. In fact as you rotate the engine the oil pump will cause an extra bit of oil to come out. It sounds as if all is well. All of the Yamahas that I've had also have a little bleed screw somewhere on the top of the block to check that there is oil getting up to the top after an oil change, it should be shown in your manual.

Never worry about asking basic questions, we're here to help.

Thanks

I have trouble understanding when its on the compression stroke tdc.
People say watch the rocker arms, is it when the valve/arm goes up or is on its lowest position yor supposed to measure? I would guess when its on the highest position just becase its hard to measure it on the lowest position haha.

I turn the engine and the valve goes down then suddenly it goes fast up, then when i turn the engine a bit more the valve slowly goes a bit more up until it starts to go down again.

Thats due to the profile of the cam acting on the cam follower (rocker arm). It needs to have a nice gentle slope to push against the valve spring to open the valve, closing it is easy as the spring helps, hence it's quick. When the valve is closed there should be a small gap between the cam follower (rocker arm) and the top of the valve. This is to allow for expansion as the engine gets hot. This is why you should check it when it's stone cold (maximum gap). Think yourself lucky you have this type of valve adjustment, bucket and shim is a whole other kettle of biscuits.
