TORQUE ADAPTOR WRENCH
The Motion Pro torque adaptor wrench is designed to be used with a torque wrench to accurately
tighten the cylinder base nuts on two-stroke engines that you cannot reach with a socket wrench.
How to use the Torque Adaptor Wrench:
When you mount the adaptor onto a torque wrench, it effectively lengthens the torque wrench. Therefore,
the torque value set on the torque wrench will not be the actual torque that you apply to the fastener.
Before using the torque adaptor, you must recalculate the torque specification listed in the engine’s
service manual. To recalculate your torque wrench when using the Motion Pro adaptor, use the extension
formula included with these instructions.

After recalculating the torque specification, write it down here for future reference.
