Ok folks this is the last chapter to this saga: Let's start with the piston.
After hours of searching for the casting symbol of a circle with the numbers 487 within it I came up with nothing. Not deterred by that I searched for the unique physical property of the piston. The obvious is the inside of the piston is not machined at all. But the real tell is the cross hatched design at the bottom, you can plainly see it in the pic. So I searched through litterally thousands of pictures of pistons to find that cross hatch design and you guessed it, I found it. Whoever it was that made the wise @ss comment in jest that the pistons were made in China, hit the nail on the head. These pistons are manufactured by the WoTech Corporation based in China. I also took the time, because I had so much else to do, to measure certain characteristics of it and found the wall thickness varies as much as .030" , not a good sign of quality.
I went to the BMW dealer and found that they still hadn't come to an agreed price of repair with RPMONE, but the bike had the new motor in it and was running as expected, no smoke and smooth as silk. I just looked at the repair shop manager and said, "I don't give a sh!t about what RPMONE is doing I got a blank check in my pocket, what's the finally cost of the R&R of the motor". He told me, I wrote the check and now I'm a happy camper because I can go on a long ride with the guys tomorrow. The new motor seems to be quieter with less top end noise and the transmission seems to shift a tad smoother. I couldn't have asked for more except for all the aggravation of the who's on first dialogue throughout the process of repairing the bike.
As for RPMONE, at some point in time they'll come to an agreement of the cost of the repair and that check will come directly to me. So basically it all evens out in the wash.
Ride safe people I got a few miles to make up..................................
