The Skidoo 670 is a snowmobile that was manufactured in 1997 by Skidoo with the official model name MX Z 670. It has a 670cc, two cylinder engine that is liquid cooled. Torquing the nuts and bolts on your Skidoo to specific values will help to make sure that you don't over-tighten them, causing stripping or breaking.
