Does anybody know about these sleds and there reliability? My cousin just bought one at haydays and I did a compression test and got 110 in the right cylinder and 120 in the left cylinder. Is this normal for these sleds? It has 4200 miles on it and it look super super clean. Also did they have the SC-10 suspension and what type of ski doo clutch did they have? any help would be great so I can give my cousin good feed back on his purchase.
