Im in need of some advice. After rebuilding my engine, i thought it was worthwhile doing the valve clearances. Got about half way through and while i was replacing one shim it didn't go into its seat right and fell down the side, only for me to helplessly watch it disapear down a bloody hole :smt013 ! I should have noticed the three holes which i think are for the oil to drain back down to the sump. Do you think if i drained the oil and took the sump off i could find the shim or what should i do. I dont want to chance running the engine with that inside.

got a magnet on a stick ? get one and have a probe .. if not, sump off and go fishing ..

reminds me there's a circlip in the depths of my zx6r ..

the magnet probe is the go.

it should be stuck at the head gasket , there is a flow restrictor in the gasket that probably would stop the shim falling through...hopefully...

Thanks guys. Now that you mention it, i remember the gasket has a cross like cut over the hole so hopefully it hasnt gone to far. The magnet on a stick sounds like a good bet so il give that a bash. If no joy, looks like the sumps coming off

only for me to helplessly watch it disapear down a bloody hole

Did you swear much?

Yep, there was a few choice words used at that moment. Its funny how its always the bikes fault lol.

I also managed to do this when doing shims on my 400L! It didnt fall all the way through, probably a couple inches down - but far enough not to be able to see it and make me expand the dictionary a bit.

The oil channels are quite small, and i couldnt find a small enough magnet on a stick type thing to pass down the hole so I ended up using a speaker magnet with a bit of electrical wire attached. As the shims weigh next to nout you can get enough charge on the end of the wire to lift it out.

Lots on ebay

And your local tool shop, auto factor and maybe even the local pound shop will have them.
