If you are going to use a SEC barrel on a KTS, it must be machined to the same specs as the SD barrel for the fitting of the Exhaust Gasket and Head Gasket. No other SEC components are eligible to be used. 12th Dec 2019

At the 15th November 2019 AIDKA council meeting the Club’s Voted 10:3 to allow the introduction of the alternative X30 components from February 2020 AIDKA conducted both Dyno and Track Testing on these components and presented this information to the council before the clubs made their decision. Testing was conducted by two drivers at two different tracks.  Similar findings were found by both drivers.  The first test was performed in race conditions while the second test was a one on one test, new vs old components. TEST RESULTS  The results can be summarized as follows: Tillotson HW-27A carby with larger reed block (29mm instead of 28mm) felt strong but in comparison to the old Tryton carby, lacked bottom end power. The New Style Pipe gave us the reverse result with increased bottom end power out of the tight corners of the track.  Without changing anything like gearing, it still maintained similar mid-range and bottom end power compared to the old pipe. The PVL ignition provided no difference in performance. When both the Tillotson HW-27A carby and New style muffler were used together there was negligible difference between the new pipe/carby and the old pipe carby combination.   For this reason, it was proposed that either new or old pipe/carby combinations could be used, but not a combination of the two. Dyno testing did show an increase in power in the lower power range but it has not shown on the track.  This may be put down to dirt karts not using the lower end power range as offer as bitumen karts do.   THE NEW RULE FOR 2020  The clubs voted to allow the following: Either combinations of the following carby & pipe Tryton Carby & 2017 Header pipe/ Exhaust combination or Tillotson HW-27A carby & one-piece exhaust Either ignition can be used with each carby/pipe combination The use of the new wider radiator is also allowed to be used with any of the AIDKA approved engines   WHY THE CHANGE?  This change was due to IAME changing the components available on new engines.   Karting Australia introduced the carby and pipe at the beginning of 2018 and the ignition at the start of 2019.   IAME...
