    Questions answered.  Will address the first couple and then dive in this afternoon to answer the rest to isolate the stiffness.

     

    1. Don’t believe the crankcase has been apart.  No scratches on the paint.
    2. Removed the pistons last night.  Rings were oiled and moved easily in the grooves.  Surprised by the gaps, .002 and .005.  Rings are flat, then a lip.  Filing these would not be easy.
    3. Connecting rods caps.  Bottom is silver, top on is not.  They are oriented in the same direction and I can read the part numbers on them.  I have taken photos through out and been careful to mark as best I can.  The bottom cap was very scratchy on the part that faces the journal.
    4. I placed the crankshaft in the case and spun it, no top half.  There is no wobble, the crankshaft does not appear to be bent.
    5. Reassemble the crankshaft in to case and lightly tighten the screws.  The attached youtube video attached.
    6. This afternoon I will reassemble with the pistons to try and isolate where the stiffness is coming from.

    8. Sorry if this post is not flowing smoothly.  I am having many problems loading the photos and replies taking place.
