Question! I recently acquired a 04 sportsman 500ho

I got this atv and it had no compression. I pulled the jug and the wrist pin was seized in the connecting rod!!!! What causes this and can I replace just the top end? There is a few burs in the connecting rod but I think I can smooth them out! Also if this is not a option and I end up doing an engine swap can I up the engine to. 6 or 700??? If so what year engine!?? Any help would be greatly appreciated!!!

Fall maintenance

I need some advice from you veteran ATV’ers.

I have a 2012 Polaris Sportsman 550 that I purchased new and use just for plowing in the winter and the occasional "chore" around my property, like hauling wood, moving a trailer, etc. It does not go out on trails or do any off roading. I take it in each fall to have the oil and filter changed and have it inspected by the mechanic. They always tell me everything looks good. Should the demand drive fluid, rear gearcase oil or transmission oil or anything else be changed at this point ( 3 years). I just want your opinions before I pose this question to the people at the place where I have it serviced.
