    Gosh, JSB55,...

    That should get you a hundred-lot from MSC or McMaster-Carr, I think.

    Hope the shipping and handling makes up the difference!

    PS: Mine came out of a dumpster, honest. (But that was 'back in the day' before the Crash o' 'O8. There has been no 'recovery' at the bottom of the food chain.)

    Exactly, Rod. The locks from Bill's Custom Cycle - and other places, he hasn't cornered the market- must be drilled about 1/16" into the lock body. The huge drawback of this method is that the new hole is now 1/64" larger than the original hole as used by the stock solid retaining pin.
    And the lock does rotate freely 360 degrees.
    The spring behind the plunger is not strong enough to push the plunger into the fork stem under any circumstances; especially if ample grease was used upon installation.
    Which reminds me that it doesn't hurt to occasionally grease the plunger on any machine in which the original lock still exists. How? Just hold the grease gun tip against the weep hole under the plunger bore, and pump away. Most of the grease will make a big blobby mess, but *some* will be forced up in and around the plunger, eventually becoming visible in the key slot. I can't tell you how many stuck plungers I've seen, but I can tell you why most fork locks fail.....
    Why *grease*? Because grease fills the voids, discouraging the formation of corrosion.

    (I know I left this conversation open for the many different ways to lubricate the lock and plunger, but as long as it's on our personal Periodic Maintenance Chart, it will have served its purpose. Just don't use WD-40; ask any locksmith.)

    Regardless of where the 'scratch' is, the correct orientation for the key slot is 90* - exactly perpendicular - to the plunger pin.

    Grease is a 'good thing', Rooster!

    But if the spring isn't strong enough to do anything, then why use it at all?

    The detente on the back of the core does everything.

    To prevent the plunger from getting 'stuck' at the back end of the bore.

    Gimme a break, Rooster!

    The detente on the core might break first?
    (You already said the spring was weak...)

    What keeps it from getting stuck forward?
    (Its obviously more likely to get pinched by the forkstem than the bore in the headstock. The "engineers" just couldn't figure out how to add a spring there!)

    I post on this forum to help others when I think I am able to, based on my experience and knowledge. NO, I do not post a lot.
    I do NOT post on this forum to argue with keyboard jockeys who apparently have nothing better to do than argue with other members- over the most asinine and trivial details which mean nothing to people who actually work on and ride their motorcycles.
    Goodbye, Cotton.
