Some Strike J Pistons due to the manufacturing process can have excess material on the inside of the piston in a localised area.
The Strike Factory apply some minor grinding to ensure no material dislodges when these pistons are being used for racing.
This is allowable, but must be done only by the Strike Factory.
No additional grinding allowed.
