    850 over bore?

    After a little fumbling with my compresion test I determined that my bike was not in need of top end work.

    I must admit though I was kind of excited about the thought of going with larger pistons. I know wiesco doesn't make a kit for us 850 guys.

    What options do we have? Does someone else make them? Or can we use larger pistons intended for some other bike?

    Soory I just found the same topic.

    Soory. Never mind. I just found the post from gs850er. He had the same question. I'll send him a PM to see if he has found any more info.

        well just woke up and was wondering....

        The 850 is just really a bored out 750 right? and I assume the cranks are the same as along with the stroke? Then my question is how big of a bore kit do people make for the 750. If its bigger that the 847cc (i believe that the exect size) You should be able to install it just like a bore kit on the 850 motor also.

        If this doesn't make sense sorry I just woke up.

          In case anyone is interested, I have for sale a set of four standard GS850 pistons with rings, and a bank of cylinders, all in perfect shape, all stock. Less than 15,000 miles on that 850 when it was taken apart.

          E-mail me at marinick@erols.com or pm me for negotiating price, shipping, etc.
