Ummm I have some Noob questions...

How do you know which is the intake and which is the exhaust valve? Maybe they are labeled? <-- I thought so, exhaust valves closest to exhaust.

Also on the video the valves seem to move up and down at the same time.

When the intake closes (up) and RT is in the view sight are both valves up and that is when you measure & adjust both at the same time? <-- Dho! I just realized... Intakes closed, valves down. Thanks Boxwrench.

Thanks t-man403. That's good insight.


Oh thanks also Smithy

ThANKS!

RT = Rear Top position
FT = Front Top position

means the cylinder is at the firing point and bothe valves are closed.
So at this point you can set the valves.

Be sure you are on the COMPRESSION stroke. It is possible to set the valves 180* off on the exhaust stroke....bad.....

Maybe this will make more sense once I look in there I don't know. I'm going to try and do this Saturday, thanks guys!
Exhaust valves are the ones closest to the exhaust pipes. RT is for the rear and FT for the front. The V Shaped arm will be able to be moved ever so slightly up and down when you are on the right stroke of the RT or FT. If not, rotate till you come to the marking again.

It's too early in the morning! "Bad" is wrong stroke for adjusting. Read my comment below "Boxwrench" and hopefully it will be a little clearer.

Bad = engine runs like fresh horse pucky......

To see if you are at Top Dead Center you can slide a Long thin rod like item ( too long to fall in all the way, non metallic better) in the plug hole and feel the piston stop going up

They're not moving at exactly the same time, the intake opens just as the exhaust closes.

This page has an animation that gives you a good look at what's going on inside cylinder as the crank turns: http://auto.howstuffworks.com/engine1.htm

As you can see, the piston will be at the top of the stroke when the exhaust closes and the intake opens, but this is not the position you want to adjust the valves. Turn the engine one more rotation to get to top dead center.

Just finished. It was bit tough. The clearances between the screw and the valves is so small. My valves did not seem to have any before I adjusted them.

Whats a sign that the valve adjustment has been done correctly?

I did not test ride it, it's still on the lift since I'll lube the spline tomorrow.

Thanks guys.

snappier performance and a soft ticking of an angry sewing machine.

I can hear the ticking, I assume it's from the new clearence on the valves, and the sewing machine sound. Performance seemed the same. Hard to tell but it did feel different. A bit smoother. Someone said a noisy engine is a happy engine with the Vol, I guess its true.

I'll keep a close eye on performance and over heating just in case something is wrong.

I would suggest to people to get new gaskets for the valve covers. Also those screws seem to strip easily, take easy there. Thanks!
