  Not surprising at all.  Talk to any requtable race shop, & they will tell you
that part of balancing & blueprinting (basic requirements) an engine for racing
includes "trueing" the crank for problems such as this.  Unless it is a billit
crank, machined from a solid piece of metal, ...... these problems exist.
  Your triumph has been running just fine this way; unless some brutal outside
force has caused this condition, the crank has probably been this way since 
birth &
will live a long & happy life.
  Just my .01 1/2 worth.
