I found out that there are 3 different set of gears (other than aluminum and fiber timing gear), 2 of which have markings of 14 & 20 and the other set is an HD version, what the 2 sets of 14 & 20 mean I havent figured out yet, my guess is pitch of the gears. All sets of gears have the same amount of teeth 27 & 54. And I did order up a set of gears today since both where wiped, should be here on Tuesday.
