The valves are with the camshaft in the microfiche.

Why not just put the whole 1100 head on it?? I think the 8V guys seek out those 1100G heads for their better flow..

Indeed I did, and I agree, you can also buy a head for what new valves cost.

BUT, yes, if you have access to valves only they are the same.

I reread his post, and he has the 1100 head already on the bike and wants to use 100 valves. Yes, the valves are the same between 1000 2 valve and 1100 2 valve.

I already have the 1100 2 valve head and the valves would not seat off. I took to my mechanic and he said the 1100 valves were bent the head is used and I still have the 1000 valves and I wanted to just use those to save money. You guys just don't know how thankful I am that info.

I bet, a full set of OEM valves is $300 if you can find them.

The valves are about that ($300.00), I also was wondering with the 1100 head do I need to use the 1100 cams or the 1000 cams?

They're the same, so which ever is in the best shape. Do use the 1100 Caps though, don't swap cam caps between heads.

To my knowledge the only differences is a slightly different shape on the exhaust port on the 1100 head, and a slightly longer stroke on the pistons. Other than that an 8v 1100G is a bored out 1000G from the base gasket up..

A new set of stockers is around $200.

Stock exhaust valves are $50 each and intakes are $25. If anyone knows of any cheaper options please share.

I got the last set of Vesrah valves for these motors on earth I am pretty sure. They threw away the dies at the Vesrah factory, and I found one set in a corner at Dynoman, for $200. The downside being one had a casting flaw and there was a bubble right on the valve surface making it unusable...

But yes, OEM are $300 a set (50 and 25), so if APE has them I sure wish they would have told me. I was under the impression they'd have to custom cut them from blanks.
