It was the same in Kansas City when I was in school.  I started on a 
Suzuki GN400 (~250lbs) and only 20% of the lights would trip.  Sometimes
it seemed temperature had an effect.  I could trip some lights when it
was hot but not when it was cold.  I traded up to a Honda 750ltd ~(500lbs)
and the ratio of lights tripped improved but not substantially.  I got to
where I would wait one cycle of the lights and if no cars were coming to 
bail me out I'd just run the red light.  

My supervisor was stopped once for running a light in this situation.  
The cop finally let him go after a good verbal lashing.

Does anyone know how these sensors work?  I had all ways assumed it was
tripped by weight until a friend said he always thought they were 
magneticly tripped.
