If you have a Junior Athlete competing in 10-12 Stock or 13-15 Stock, that rider will be required to have a restrictor plate affixed to the SX-R Ski.  The plate fits between the throttle body and the damper in the intake line of the watercraft.  These restrictor plates reduce the intake to 26mm in an effort to reduce the top speed that can be achieved on the race track.

  Orders begin today and the anticipated ship date is August 30, 2017.  Orders will only ship to addresses in the Continental United States.  Plates are expected to arrive, at IJSBA, by Monday (28th) and gaskets are expected to arrive by Tuesday (29th). 

  Persons using these restrictor plates do so at their own risk and IJSBA does not warrant any particular result nor does IJSBA warrant that there are no negative consequences associated with the use of these restrictor plates.  The use of these restrictor plates could cause equipment damage or bodily injury.  All racing is dangerous.  The use of a restrictor plate should not lead to a false sense that racing is any safer than racing without the use of a restrictor plate.

IJSBA is limited to 100 units on the first offering period.
