a)    No aftermarket ECU’s, stock appearing ECU only. ECU must be a production ECU that was originally supplied by the same manufacturer as the engine. Racing ECU’s may be used, as long as they were originally supplied by the same manufacturer as the engine. Ex: Honda motorcycle engines must run ECU’s that were supplied by Honda on their motorcycle engines.  Re-flashing of ECU and factory race ECU’s are allowed. Rev limit for all 600cc (nothing larger than 600cc) engines is 16,100 rpms. Rev limit for all 636cc engines is 14, 800 rpms. U6SA specified Rev Limit must remain intact at all times (no switched or gear specific limiters). If a computer is hooked up to check the ECU it must be set to U6SA specified rpm’s, no tolerance. See specifications list for RPM limits.

a)    No mechanically forced induction (turbo charging, supercharging)

b)    Any carburetors may be used on any engine, regardless of year of engine.

i)     Note: Switching to carburetors on engines that came with fuel injection usually increases the rev limiter due to the removal of the injectors as the ECU cuts fuel to limit rpm’s before it cuts the ignition. A re-flash of the ECU will be required if using carburetors in order to comply with the rev limit rule 7. a)

c)    If the engine did not come from the factory with fuel injection, fuel injection may not be used.

9)    Exhaust
