BRP rocking those chrome rims way back in 2000, so awesome lol

Welcome to the site, Lance, sure hope you can sort the little gem back out. Couple of things kicking around in my head, thought I'd share:

There were 500cc and 650cc traxter/quests, same powertrain as the John Deere buck, so that may explain the differences in pistons you're finding.

Speaking of differences, that 2017 "Traxter" piston you're looking at above, that's BRP's nickname for the overseas Defenders. Not sure why they're trying to confuse you, but it looks like they succeeded. You're gonna want to stick with hunting down those early 2000 model years parts bikes.

@Ducvet @buckext y'all got any advice for the guy?

There isnt much info out there about these machines, which I find odd

I don't, unfortunately. Think about it: the internet was pretty young, way back at the turn of the century. Communities and forums like this one hadn't even gotten their starts yet. That bike went out of production right about the time this forum got its legs, and it wasn't exactly sold in the numbers say a Honda Fourtrax was, so yeah, I can see where you're going to encounter some trouble sourcing good info on it.
