FYI, here's a used high mileage TZ3750 1X2 piston. They came out of a TZ375 ie a TZ250E with a 409-70 top end that ran a couple of season with AHRMA before I sold the bike and kept the top end for another project that's still in stasis. You can see where it slapped against the intake port at BDC as it reversed direction.







Don't get excited by the image name. That's just what happened when I sucked them off the camera onto my PC.

Do you know how many miles that piston has run, teazer?

That piston came out of a motor that broke the other rod after it hydrolocked and was started on rollers before I owned the bike. It had done 2 seasons IIRC including Daytona. I'm going to guess around 200 miles all up maybe more. It did AHRMA Midwest and some WERA events.
