I just bought a 1997 Mach Z from North Battleford Sask and it didn't run at all like it did when I picked it up. I checked the elevations of Rimbey and North Battleford and Rimbey is 3100ft and N.B. is 1800ft. I checked the mains and it has 360s in it. My Ski doo race manual is from 99 and doesn't have any specs for the 97s with the 809 triple. The 98 Mach Zs had 300s from factory, so I'd just like to know what it came with from the factory. Thanks for any help Doo guys.
