I know this is a little off topic but just got my zero back yesterday and engine replacement costed almost 5 grand. Would a sled engine cost almost 10k to replace today if rod blows thru cylinder like my zero did? Only 364 hours on this engine too. I got new updated engine brigs had trouble with older 27 hp efi engine I had and changed them. Only one year warranty available on engine. No extended warranty 😂. 850 might be worth it for four years if you plan to ride it passed 5000 miles or a few hundred hours.
