    Question Flex Hones

    I need some input. Tell me if you think these three gpr cylinders would benefit from useing a flex hone such as the ones the watcon sells to clean them up or would it just be a waste of my time.

    If it would be a good idea, how hard is it to do?

    Any and all input is appreciated!

    Thanks,
    -Jon

    flexhones

    After years of racing mx , i use them eveytime i re ring or do a top end. Breaks the glaze on the cylinder walls and gives the rings a good start on sealing. the trick is to washes the cylinders with soap and hot water throughly. Then wipe them down with a paper towel and a little WD-40. Assemble and take it easy for the first 5 minutes or so, let it cool down. Then ride it.

    Looks like just normal wear to me. Unless you are putting in new
    piston and rings, I would just leave the bore the same. I don't think you
    would see any difference in compression and seal.

    Honing cylinders

    A "deglazing" hone is always beneficial when rebuilding most any motor, as it aids with ring sealing, and break-in. Deglazing does not "bore" the cylinder or remove any measurable amount of material. You would use a "Sunnen' style hone or a boring bar to actually remove enough material to alter and/or change the bore size.
    Be sure to use actual honing oil durning this process, not Solvent or WD-40.
    Thanks,
    Randy

    What type of hone do you use to hone nicasil? Doesn't it take a special type?

    What material is it made of? Where can you get one? How much $$$$.

    flexhones

    Guys, i got mine years ago at a local auto parts store, before the introduction of the new cylinders, they still work for me, so i don't believe there are any 'special' ones. The main trick as i outlined earlier is to clean,clean, clean them before you start the install.
