Snapped a valve??

[92MTX]

Anyone here ever heard of a valve head snapping off on a gen 1-2??
I am on another site, they don't know what a damn SHO is..
Trying to tell me the valves snap off.. Rods break, cranks break..
MAYBE pushing a lot of boost, but unmodified??
Basically say that the Yamaha is a piece of **** engine
I am about ready to come to blows with these retards..

It can happen, but its not very likley.

it would be more likely for a valve spring to break but the only spring that I know of breaking was a SHOSHOP spring.
