When it was time to replace mine I yarded out the fix kit and went back to standard sized Wiseco pistons.

IMO the fix kit can cause as many issues as it aims to solve. I've ran without a fix kit for four years now, I haven't had any issues with either Wiseco forged or Pro-X cast pistons in that time.

Adding weight to the primary was a plus in my opinion I have had them in for 1500 miles with no issues

Not my experiance but that's fine.

My pistons have these numbers on them:

8719B

11226M08500

I believe the second is the part number, but I can't find anything when I search for it. I'd call Wiseco directly with that second number, it may be a proprietary design, or an Arctic Cat piston.

I’ve changed pistons in my 14 Pro three times now. The first 2 sets were 111226M08500. Same as ABMax. However, my latest set-last week-were 12127M08500. Cycle Works took them out of a fix kit and sold them to me. I cannot visualize the difference-if any- because they are already installed and running.
