The head to piston measurement can be checked with a Vernier caliper with the spark plug removed from the gasket surface of the spark plug down through the spark plug hole to the rear of the hole to the piston top at TDC (rotate the crank 360 degrees) and should be 1.275″ to 1.305″.

The ignition timing (flywheel orientation) can be checked by installing a screw in dial indicator in the spark plug hole, zeroing the dial at IDC, and rotate the crank backwards and at .090″ to .105″. The back edge of the raised area timing tab of the flywheel should be even with the back edge of the cast in timing tab on the crank case.

The ignition timing can also be checked by making sure the ignition pick up is in the stock location and no modification.

  • Tech inspector reserves the right to confiscate any parts deemed illegal.

The fact that an infraction has not been noted or discovered does not make it legal.  All decisions made by Tech Officials are Final, but the Technical Inspector cannot change any existing rules without a vote from the members of the Association.


All cars must go through a full technical inspection prior to racing in any MSRS event.  Preseason tech will take place on a minimum of two (2) dates prior to the start of the racing season.  If you cannot make one of these dates, or you have a new car to register with the MSRS you must schedule a time for inspection with the Technical Inspector (at their convenience) for inspection of your cur.


Technical inspection may occur before and/or after a race and will include, but is not limited to checking rev limiters and brakes.  MSRS Tech Officials may at their discretion check fuel, weight, or for any rule infraction before or after any race.

You must have enough fuel in your fuel cell after the race for the tester if fuel testing takes place or you will be disqualified.

You cannot add fuel after a race.


The purpose of the protest is to provide a “safety value” to help keep the series competitive and to keep the cost of racing affordable.  Only current owners of the MSRS cars may protest a component.  Any specific components of a competitor’s car may be protested by any owner in that feature after the race in the amount designated in terms of cash or certified check.

The protest and full payment (in cash or certified check) must be presented to the MSRS Tech inspector no later than the start of tech after the race.  Once a protest is made, it may not be withdrawn.  All purse und points will be distributed after a decision on the protest has been made.  Tech inspectors will not accept verbal protest or protest in which the required protest fee not accompanies. A protest must and will be put in writing by the protester.

The protested component will be removed if needed from the car, made available for inspection by the protesting owner and delivered to a MSRS tech inspector for inspection.  The following people will be permitted to be present at the protest site, MSRS tech officials, the protesting owner, the protested owner and crew and a speedway management representative.  If a decision at the track cannot be made, then the component will be sent to an authorized agent MSRS for a final decision on legality.  On a protest, it is the protested owners’ duty to prove his legality, not the MSRS tech officials or protesters’ owner duty to prove the violation.


After inspection, if the protested component is found illegal, the owner of the car will be disqualified from that event, forfeit all prizes and points earned at the event and may face possibility of more penalties at the discretion of MSRS Officials.  The protest money will be returned to the team filing the protest.  The owner who was found illegal will be responsible for inspection fees and shipping charges if needed.


If the owner of the protested car does not allow inspection under these terms, he or she will be disqualified, forfeit all points, purse monies, prizes and awards earned at that event and possible suffer more penalties as determined by MSRS Officials. The car will also be suspended from competition.
