2003-2004 Yamaha RX Mountain Tuning

Yamaha is suggesting the use of their clutching specifications for their 2005 RX-1 Mountain on all 2003 and 2004 model year RX-1 Mountain sleds. These earlier models have shown low shift RPM or a drop of shift RPM in some conditions and at some elevations.

The 2005 version featured a different calibration. Applying the 2005 specs to a 2003 or 2004 RX-1 Mountain will minimize the shift RPM loss at higher elevations. The recommendations, of course, are based on stock units with all other calibrations at Yamaha recommended settings. Refer to a 2005 (or 2006) Yamaha Technical Update manual to locate a 2005 RX-1 Mountain specification sheet for the new specifications.
