The following information should assist teams and competitors with information regarding the difference between UT1 & UT2 engines and further the correct carburettor to use with each engine.

​

  • The rules surrounding this have have remained unchanged since the introduction of the UT2 engine however many new competitors have joined the series since then and may be confused about the difference.

  • It should be stressed that using the correct carbies & parts provides very good parity.​                                                                                 

  • All carburettors must be "as supplied" from Honda with the exception of changing the main jet to those allowed.                                                     

  • Engine numbers for UT2 engines will always start with "GCBTT". Above the engine number will be "QX2"

  • Engine numbers for UH2 engines will always start with "GCBDH". Above the engine number will be "QX2"                                                   

  • Engine numbers for UT1 can vary. "GCAHT" or "GCACT" and "QXU"

  • Any of the above carburettors can use a genuine Honda 72, 75 or 78 jet
