bent valves on kz750 was created by imyk
I have at least two bent exhaust valves on a 1980 KZ750H. Please help me out with how to proceed. I don't really have a salvage yard nearby. I'm hoping someone here will have an extra set.

thanks in advance

First you need to tell us what kind of 750 you have. Is she a 4 cylinder or a 2 cylinder? What year is it? Are you gonna pull the head yourself and change the valves or have a shop do it? ebay will be your best bet, I have picked up 4 or 5 valves for my 650 on the cheap there. Usually you can find them for about $12 (for the 650's at least)

bought it because I was told it would never run again...I like to prove people wrong.

I think the H model is a four hole engine.

If it was a 750 twin, I have a full set of used valves for one I would sell for peanuts (I put in a new set last time).

I also got the new valves off ebay and the prices were very good... like $12 each or something like that.

I also have a full set of NOS (brand new) Kawi valve guides for the 750 twin I will sell at a big discount. I bought them thinking mine would need replacing and the ones in the head show zero wear so they didn't need them.

Its a 4 cylinder LTD model. It seems to kind of be a hybrid, but I think the GPZ has the same head.
I'm no mechanic, but I have one now who is looking for parts. We think the best way to proceed is to replace the head, but are certainly open to rebuilding if we can find parts.

If you decide to have the head rebuilt, we can do it and if we can't find valves, we make them.
