The 2005 Mach Z was delivered with the TRA clickers set at #6, and this allowed the mighty twin to over-rev. Most riders simply turned the clickers down to #1 or #2, and while this tamed the peak operating RPM it tended to cause too much mass being thrown at the lower shift ratios, depending on conditions.

One of the hottest set-ups for the 2005 Mach Z was to install a set of lighter aluminum arms with an adjustable pin kit, typically set to 22 grams. Many shops were doing this using the Dalton Aluminum TRA arms for the Mach Z, along with the Dalton adjustable pin kit, while others used a Thunder Shift Kit from Fett Brothers Performance. This allowed them to run the stock spring in the primary and all of the stock secondary components. Set the clickers so you spin the twin at 7850 RPM and hang on. Tight.

For 2006, Ski-Doo tells us all of their 1000 SDI models can be enhanced for optimum performance and top speed. Mach Z and Renegade 1000s can install a 25mm set screw (part #206 262 599) into each TRA pin, and set the clickers to #2 or #3 to reach the target operating RPM of 7850.

Summit models used at sea-level (below 2000 feet elevation) can install a long threaded pin (#417 222 595) into each arm along with the 25mm set screws mentioned above. Again, set TRA clickers to # 2 or #3 to reach the target 7850 RPM
