Glad to hear they made it...only 7 days...Canada Post is pretty good. Not as good as Amazon but still pretty good.

Looks like this will work. I may hone them more when I set up for the Andrews cams. Might make them more even as well.

JUST PLAIN JUNK. Seems good parts are getting few and far between. Was looking at exhaust valves and the used ones listed you can't even see. This guys obviously trying to pull a fast one.

Too dark to see.

This guys a crook.

I bought 4 new ones. The ones I have in the bike now I tipped. Getting some popping so they may be like the Doremi valves I took out.

I think I'm ready to do the switch. B)

You can still get OEM valves but only for intake. (or is it exhaust?) I looked because I was interested in a set for my engine rebuild.

Are you happy with the Doremi valves Steve?

They didn't seem to hold up as well as OEM. I'll know more when I take the intakes out this time. They appeared to be lighter but I weighed them and they're not by much.

That head looks amazing, compared to the head you started with Steve!

I looked at the fleabay used valves you posted. Anyone buying valves should know that the sealing area's on the valves themselves pit over time, and cannot be machine ground out without removing the margin area on the valve. That leaves a sharp edge that will glow red, much like a gasket fire ring sticking in the the combustion area. Both cause detonation hence engine failure. Also, they sink so far into the head, that the valves cannot be set. It can barely be seen in silhouette on in the dark pictures. who cares what the tops look like? What a tool!

Note.. out of all of those dark pictures, the only ones that really mean anything would be the valve sealing surface and stem diameter / length, which are not shown at all.

Total junk: Notice it says "no returns"?


This is a actual valve grinding machine video. Note the valve he grinds has no valve margin left and is junk.

He may not accept returns but a not as described case will get him. :evil: Ebay has gone the way of CL. Now they are charging taxes for states that don't even charge them. THIS SHT HAS TO STOP. :angry: You search for a specific item and they show all kinds of crap you don't want. I'm constantly getting emails with offers I didn't ask for. They all go to my spam folder then get deleted. Been using their site to find an item, use that info to search for a better price. Got a igniter for my Maytag oven for 1/3 the price using this method with free shipping to boot. :lol:
If it's not a clear pic don't buy it. Got a email it has been relisted. Good, he can fondle his junk while I get my new valves and RIDE THE PISS OUT OF THE BIKE. :woohoo:
I have some that would work but best to start with new. B)

Kawasaki has a spec for the head thickness at the seal. I don't know what it is off the top of my head but I read it when I was looking at the other specs.

Steve, I am surprised that the Doremi valves are that much lighter...and I wonder why. If they are the same length and diameter (hence same volume of metal) then they must be made of an alloy to make them lighter. Then comes the question...is a lighter valve better or worse?? I'm thinking better but I really don't know.

They seem to be the same but didn't hold up like OEM.

I imagine these are lighter and stronger but would they be worth it on a street bike?

There are other valves but I just wanted something new and affordable to use in this junk head.

Happens so much with used valves. You got to look for the later MarkII smog heads. They used Nitrated valves The one's that looked blackish. Plus the exhaust were 100% 304 stainless steel. I have a nice head I'll finish after Holiday season. Need to paint it black, been sitting like the rest of everything. But I taped it up, then sat and aerosol cans sprayed. Now its covered in a silicone film. got to clean over! Ha! WTF me?
And valve tip should have .020 here is a manual page. And some extra pictures. Funny thing for prices of valves? Buy some Titanium valves for a Z1-KZ Pricey. But for size and material these titanium intakes for the Blower Hemi Gasser are only $180 a piece. A little bigger than a Z.
Plus I tip valves on the lathe of course. I sold a head over a year ago, I tipped them all to bolt in with 260-270 shims. I never take more than .015-.020 of of the tips Just getting carried away here. But work with what you got Steve. Pretend it's a harley put it together and beat the piss out of it!

One drawback about running Ti22 valves in a Kz head is you have to replace the valve seats with a softer material like bronze.

If you don't replace the valve seats, your valve clearance will change dramatically in just a short time of running!!!!

When you pick up a Ti22 valve for the first time, you will not believe how light they really are!!!!!!!!
