    Couldn’t agree more about the buzzwangle,after messing about with a degree disc on the threads of my crank I set timing with my buzzwangle in 5 minutes brilliant bit of kit.

    Can anyone tell me the recommended port transfer timing for a standard GP200.
    In the past it looks like a Spanish casing has been used, so at present my squish is very high.
    Therefore, I’m looking to put spacer on but need port transfer setting first.
