    Holes in Pistons Anyone?

    So he didnt start a thread here yet so thought I would pick your brains while Chris tries to see what he can.

    Do you have a great road adventure that you would like to share? How about a bike repair gone bad? Put your story here and share it with the rest of us.

    Pick our brains how? You have to ask a question to get an answer.

      Yea I had one of those on the 550.

      For me I was holding the throttle wide open but I had a faulty
      petcock which caused the bike to run lean under load.

      I cleaned out the sump, replaced the piston and it runs.
      I also replaced the petcock.

      In my case the cylinder was also lightly scored but I didn't
      bother honing it. I should've looked at getting a new set
      of low mileage cylinders on e-bay.

      The result is that a little oil gets into that cylinder and slowly
      fouls it. Not a big deal. Maybe after another 20-30k more miles I'll
      strip it down again and replace the cylinders.

        Yup, I had one like that on a 1000s that had been laid up and not cleaned the carbs properly, but in my case i continued on to my destination another 50 miles (before mobile phones) then put a new piston/rings, cleaned the sump & carbs. bores were fine on mine.

        Don't say can't, as anything is possible with time and effort, but, if you don't have time things get tougher and require more effort.

          last time I saw that, was a 74 RD250 with a kid who didnt know how to set his ignition timing, and also screwed up his fuel mix. showed up at my place, we popped the heads off, BAM there it was. looked just like that one too.

            RD's are a completly different bag of worms, I knew, still know how to set the timing and I still used to pop a piston every week! NGK didn't do a B10 ES
            Every couple of months We would weld a row of them up at work.
            Nostalga ain't what it used to be thank God.
            I remember the man in the bike shop trying to be helpful telling me that a B8 was a softer plug but if you were a hard rider you would need a B9 My reply was that I would take a B10 fell on deaf ears.

                        About a 800 miles(?) from home in Humboltd County CA.
                        There was a Uhaul not too far away. THAT was expensive.

                          I know that feeling only too well.

                          We had to rent a U-Haul van in Durango, Colorado to get my wife's bike back to oHIo, back in '04.

                          To add insult to injury, halfway across Kansas, my Voyager broke, too, so we had to squeeze TWO bikes into that 10' van.

                            uhaul has nothing on how Chris got the bike out.

                            An epic around the world expedition on a classic 1982 Suzuki GS850 motorcycle to end world hunger.
