    Would like free 2.5mm valve shim

    Maybe I'm too bold to ask, but I'm doing a valve adjustment on my '88 K75C. Fuel mileage was about 35.5mpg, and so I'm going through procedures that might rectify this. Bike has relatively low miles, but who knows what the PO did?

    I used the Lively tools and they work great. Front exhaust valve is tight with .216mm clearance. Middle exhaust valve is tight with .229mm clearance. Front had a 2.6mm shim, middle had a 2.55mm shim. The front needs a 2.55mm shim to get a .266mm gap, so I'll reuse the middle's for this. The middle needs a 2.5 to get the gap at .279.

    At Bob's, a 2.5 shim is over $13 with $10 shipping.

    Does anyone have a 2.5mm shim they could send me? Between cardboard taped in an envelope would be a postage stamp.

    Sorry for begging, but can you see what you could do for me?

    Thanks al!

    I have one you can have. I think I will have to put it in a package that is about $4.50 prepaid. Let me know.

    I don't have one that size, but I have sold quite a few extras on ebay over the years - I just tape them to a piece of thin cardboard and put them in a regular mail envelope. They weight less than an ounce so they qualify for 1st class mailing. However, the first time I sent one, I went to the post office and the lady told me there was an extra (23 cent?) charge for not having a flat envelope. From then on, I just put a 2nd stamp on the envelope and they have all found their new homes without problem.

    Also, some dealers will trade out one shim for another.

    Good luck!
