park brakes never work like they should. i have taken all the funny things like that off. park brake, key, headlight, oil light....
my rules:
BRAKES:stop at an angle on a hill/find a rock to chock a wheel (preferrably leuco gabbro

)...or dont stop at all (my personal favorite)
HEAD LIGHT: only ride while the sun is up, if you have to ride at night where the hang are you going in the first place!??
KEY: park where skebangers cant steal your bike, pull off the spark plug lead or dont stop at all. Beside if someone wanted to steal your bike they will spend 20min looking for the key which you removed and so you will have the opportunity to bash them over the head with tree.
OIL LIGHT: premix...why do you need a light to tell you the oil is finished anyway? that light should be in your brain and go on before you even start the bike
Quite funny hey, blasters are sparsely vegetated with "civilized goodies" and then we go and rip them off anyway...
Sorry i guess this doesnt really help you, i just felt some inspirational thoughts coming on
