"Turn the screw slowly clockwise (right), pumping the gas pedal after each quarter turn."
ahahaha funny stuff, i've seen that on ebay before, it probably works.. to an extent a bit like a totally pathetic power commander messes with the fuelling gives you an extra 5 bhp and 20 bloody horrible problems
i imagine insurance companies would give all their employees a paid vacation at your expense just for putting somethin like that on your bike, not to mention voided warranties etc
the shocking thing is people actually buy those and use them...
whatever floats ya boat
