Here is the rusted rear bearing from my newly purchased Saito 1.00, the front seems OK but at 11 bucks for the set and free shipping from BOCA I'll change it anyway. The cam is fine, the crank is fine, The rod was frozen in the piston and the ring was stuck in its groove., I shot it up with PB Blaster and laid the piston on my shop heater and in about 10 minutes both the rod and the ring were completely free.
