I recently picked up this bike and started working on it. I took the cylinder off tonight and started checking everything. When I first started working on it I took the ignition cover off to check the flywheel for movement in the crank and it was good there. But after getting the cylinder off and the piston off it feels like the rod has excessive movement in it side to side. But it didn't have any up and down movement in the rod bearing. I rotated the the crank so that the rod was at the bottom and the rod would not touch the crank halves. So does anyone have the service limit on these rod bearing or can you tell me if it is ok?
