Vintage Dirt Bike Q & A

Does anyone know the stock timing setting for the '75-'78 CR125M's?

The '74 timing is 19 degrees BTDC, with the CDI adding about another 12 degrees or so advance below 6,000 rpm. I have a feeling that when they changed the rotor/stator set in '75 and again in '76 they may have advanced the timing, but I'd like to confirm it from a Honda manual if possible. The CDI boxes are the same for all years of CR125M.

Thanks,
Ray
