Hey everyone so I have a had several pro Rmk’s over the years. 13,15,16,and now a 18. I am looking to upgrade again this year. I always buy slightly used so I am looking at a 19,20 850. I have heard lots of rumours about the 850 engine having bearing issues? Wondering if this only affected some sleds and what year they updated and fixed the issue? Should I avoid the 850 and look for a boosted 800? Wanting some more power this year
