Anybody notice they fit loose? And damage the pistons after a few miles, pounding the clip grooves, causing burrs?

Yes, many of the rings supplied by JCC are the wrong size. Throw them in your junk drawer and go to your nearest parts store with your snap ring pliers and find the next bigger size.
The loose rings may fall out and I have seen a few damaged cylinders because of it. Jim

They are made to be inserted properly with this:

Convential methods usually result in over/localized bending of the circlip, thus the loose fit you've observed. Properly installed, those clips are as reliable as anything else.
Of course. Thanks for the tip. Do you have a P/N from McMaster? Or NAPA? Maybe a pic?debby said:concours said:OP, are you using a proper insertion tool for these modern tabless circlips? Or working them in using no specific tools? (screwdriver, or the like)

The circlips are the tab-type so your suggestion, well-intentioned though it may have been, is irrelevant. The supplied circlips are simply the wrong size. I got some from my local NAPA store that fit correctly. McMaster-Carr also sells them but you have to buy a bag of 50.

They're just standard circlips so the photo wouldn't be very interesting. The parts guy at NAPA picked them from a box of various-sized circlips (like they do for o-rings) so I don't have a NAPA part number. Basically you just need the next size larger than what EMGO/JCC supply. I can look for the McMaster part number when I get home. I did buy a bag of them so now I have a lifetime supply!

Wiseco's are best for four strokes and ashtrays.. oops, that's another discussion.debby said:concours said:Ok, so you mean standard internal retaining rings, punched from flat material, complete with holes in the ears for the circlip tool to engage?
^this.
standard circlip pliers work well.
That tool you found would have been useful when I put a new piston in my Maico a couple of years ago. That piston (Wiseco) did use wire circlips.
