Did not see the whole thread but if someone is suggesting doom and gloom after someone else used a magnet to help get shims out then I would like to point out the fact that forceful tapping to a magnetized item quickly removes magnetism ... hmm valve shim is getting a "tap" thousands of times a minute ... even though not so forcefull I am thinking whatever residual magnetism induced by picking out shim with a magnet is gonna FAST be gone! Yes it's theory but so is it theory that it may cause problems in the first place. I say I don't think the sky is falling today on this one ************************************** Get a sneak peek of the all-new AOL at http://discover.aol.com/memed/aolcom30tour [Non-text portions of this message have been removed]

Did not see the whole thread but if someone is suggesting doom and gloom after someone else used a magnet to help get Valve clearance adjustment shims out of their bucket then I would like to point out the fact that forceful tapping to a casually magnetized item quickly removes such magnetism ... hmm I'll go out on a limb here and hypothesize that since these valve shims is getting a nice little (albeit oil cushioned I admit) "tap" thousands of times a minute that then even though said tap is not so force full I am nevertheless assuming that whatever residual magnetism induced by briefly picking out shims with a magnet is going to FAST be OUT TEE. Yes this is my untested theory but so I imagine was it a theory that it may begin a chain of events leading to a catastrophic demise of your engine in the first place. I say I don't think the sky is falling today on this one. But I also agree that a magnet is hard pressed to overcome the suction so safe or unsafe why bother (yes I been there done that) What I did find helpful in loosening said suction was to irrigate it with an oil displacing solvent (preferably one that can't damage anything or leave any harm full residue or anything. ************************************** Get a sneak peek of the all-new AOL at http://discover.aol.com/memed/aolcom30tour [Non-text portions of this message have been removed]

<><><><><><><> <><><><><><><> joyteachern, I've got to say I agree with you about magnetizing a shim. In my opinion it isn't an issue to worry about. Of course I wouldn't go rubbing a magnet all over the shim playing with it either. : ) I was taught to be careful with bearings as if a bearing gets magnetized it'll probably attract stuff that you don't want touching it. I often use a magnet and compressed air to release a shim from a bucket. I put the magnet on a stick so it touches the shim and then give a small shot of air at the edge of the shim and bucket. Usually it pops them right out and the magnet captures the shim for easy retrieval. Just one more way to remove a shim. On a similar note... When I go to the dealer to get shims I take a digital caliper with me. I measure each shim I'm getting to make sure I get the correct size for the job. The Kawasaki KLR650 and the BMW F650 both take shims that are 29mm in diameter. I don't know what takes the 29.5mm shims but I know they are out there. I usually can't tell the difference unless I have a correct shim to compare sizes.

Sounds about right--thats why I got a new 07. The 08's a smogger and its only the beginning. Next year they'll prolly retard the cam timing............Gotta satisfy the feds.
