    Hey guys,

    Weird one, just reassembling the valves on the ZXR, and realised that there was no 'valve spring seat' when I removed them initially?

    Am I missing something here?

    Now, looking into the spring locations, 3 of them have a different look to the spring location, but none of them have the valve spring seat washer...

    I presume that they do all need the valve spring seat washer thing...?

    Looking at that pic - they're still down there, I went through a bit of an ordeal recently attempting to lift them out on an FZR250 head - they've got oil around and underneath them and they're not to keen on coming out, or falling out.

    A dental pick down there and you'll see them rotate where they're still there.

    Two small neodymium magnets taped to a piece of plastic tubing did the trick for lifting them out.

    Use a pick or a magnet to check if they are actually there, they get stuck.

    If they are indeed not there, they are necessary otherwise the hard steel spring will wear into the aluminium head.

    In a pinch, you can use hardened steel washers so long as they fit and the height is close enough.

    Cheers guys!

    Tried a magnet and compressed air, can't see any movement, popped down to the bike shop and he also thinks they aren't in there

    Luckily I did order 16 of them so easy fix
