This Modifications can be done on the 97 & Up SX700 & 600 Triple Style Motors and the 97 & Up 500 & 600 Twin Style Motors non Power Valved.

See the attached pictures to show what needs to be notched in the reed stoppers. Notch size is 24mm tapered to 18mm wide and 4 mm deep. You can do this on a bench grinder after you take the reed stoppers off. If you do this notch you don't have to get reed spacers. They do the same thing. This mod and the reed
spacers unblock the intake port for a straighter flow into the case on the top side of the reed stopper (Notch goes Up).
