as some of you seen im building my k7 up a bit this winter and i would love to change the gearing BUT i hate how inaccurate the speedometer is now, so after i change that i will go insane. to fix that i figured i buy a speedometer-correction-device like a speedometer or yellow box
my question, since im sure somebody on this board got one or the other, is which one is easyer (i like easy:sneaky)
to use and install and/or better?
thanks for the help in advance
