For optimum performance and top speed at elevations below 2000 feet, a 25mm set screw (Ski-Doo #206 262 599) should be installed (with Blue Loctite) in each lever (arm) of the TRA primary clutch on the 2006 & 2007 Ski-Doo Mach Z and Renegade X 1000 models. The TRA clickers should then be adjusted to #2 or #3, according to your operating RPM. The target shift RPM of the 995 engine is 7850 RPM, no higher. This should only be installed by a qualified technician, following the specific procedures outlined in the appropriate â€œShop Manualâ€ for the model.
We’re told this modification is not covered under warranty, and that this is â€œthe only modification allowed by BRP that will not void the warrantyâ€.
