As of this past Saturday, I have first hand knowledge about the POS POG failure. My bike just turned 40k and has been running fine. I got it out of the garage and decided to run down to the store Sat evening. I was very lucky, got about 1/4 mile from home when the oil light came on. Shut bike down, waited a few minutes and started back up. Light continued to stay on so I immidately returned home and parked.
Pulled side cover, removed clutch and there it was. The plastic oil gear with all the top section of teeth stripped off.
I have contacted Bob about the Judges steel replacement gear and he said he would get back to me. Hasn't as of yet.
Might add that to remove the plastic gear I took a screwdriver and wedged the bottom of the gear to prevent it from turning, then took a sharp knife and small hammer and began splitting at the top. Rolled it and did the same again and it came right off in two pieces.
