Continuing to tear down the engine of the 1981 Suzuki GS650L to replace the broken cam chain tensioner. Next to come off was the cylinders and pistons. All of the bolts were previously removed with the cylinder head removal, so it was just a matter of lifting the cylinders off of the studs.

And the crankcase with the pistons and connecting rods exposed and getting closer to removal of the broken rear timing chain guide:
It is amazing how much crud gets in and around the studs that tie everything together in the top end of the engine.
Next is removal of the pistons from the connecting rods. First is removing the cir-clip at the outside end of the wrist pin. I was expecting a clip with holes at the ends to grab with snap ring pliers, but it was just a heavy gauge wire. All came out easily except the No. 2 piston where the cir-clip was not exposed at the slot to grab it. Rags were placed under each piston so that the cir-clip would not be dropped lower into the engine even though the whole engine case is going to be split apart to replace the rear timing chain guide.
Pistons 3 and 4, the wrist pins slid out with just finger pressure.
And the three components of the piston, wrist pin, and cir-clip:
Pistons 1 and 2 were a little bit more difficult to push the wrist pins through with finger pressure alone, so I used a pin puller. Still didn’t need to use a wrench to pull them out, but it was much easier with something to grasp and pull them out.
With these components removed, I will now spend some time making sure that the cylinders, pistons, and rings are still within service limits, or if any further modifications need to be made.
