Gt550 ignition timeing

Postby Stevengt750 » Mon May 13, 2019 8:56 am

Hi there I have a strobe light with adjustable value on it for the timing and would like to set each cylinder up with the timing marks and wondered how many degrees before top dead centre the timing should be on a 1973 gt550 any ideas would be appreciated also if that works I would like to check and set up the timing on a 1972 750j would that be the same timeing as the 550 or does it have a different value cheers Steve

These bikes have a Fixed timing with no advance or retard. So just set it with timing marks. If you want to you can check the marks are accurate using a TDC gauge. Remember these bikes are not highly tuned so exact timing is not strictly necessary.

I would set it to 0 degrees and go off the marks(pointers)
