broken timing bolt
It is a long, thin bolt. It is easily over-tightened. Best to install "just firm plus a little more" with a drop of blue locktite.

Put the cam in a drill press and drill the old bolt with a left hand drill bit.
That mechanical advance unit is cave man stuff, and on a 1990 it is the weak link in the entire motorcycle.
Toss that mechanical advance unit into the scrap bin and install an electronic ignition system such as a Dyna 2000i.
