Motor Mount Instructions

4-Cycle  Instructions

Our mounts have been engineered to be superior in performance and fit, and are recommended specifically by Briggs Racing! However, the following precautions should be taken when mounting the mount to your motor:
  1. Install studs finger tight into upper mount and test fit to determine what offset is best for your application,
check for proper chain alignment. Once you have determined optimum location for the set screws,
remove set screws, clean set screws and tapped holes thoroughly and re-install using Loctite making sure not to tighten set screws too far into plate that they protrude completely through which will obstruct upper mount from moving freely across the base plate.
  2. Check to make sure the upper mount slides easily across the base plate (EZ-Set mounts only) with
the clamp bolts tightened making sure they don’t protrude completely through the base plate!
  4. Check to see that the motor is sitting flat on the frame rails and is not sitting up on a weld or
something else before tightening the clamps down.
  5. Enjoy!

2-Cycle  Instructions

 Our mounts have been engineered to be superior in performance and fit. However, the following precautions should be taken when mounting the mount to your motor:
1. Check to make sure that none of your motor mounting bolts are bottoming out in your engine by screwing
each one of them in individually. Also make sure you have at least 16mm of engagement into the motor,
less will result in stripping the threads on the motor!
2. Caution should be taken when mounting the up-right (Yamaha 3rd bearing mounts only) to the motor mount.
Do not put the crankshaft into a bind by twisting the up-right when tightening the screws.
Clutch nut should be check for excessive run-out. More than .005” TIR is too much.
3. Check to make sure the upper mount slides easily across the base plate (EZ-Set mounts only) with the clamp
bolts tightened making sure they don’t protrude completely through the base plate!
4. Check to see that the motor is sitting flat on the frame rails and is not sitting up on a weld or something else
before tightening the clamps down.
