It can be done.. I have already taken apart my friends gauge and mine as well , , lmfao , i couldnt convince him on a trade , j/k , but i know it will work , it will take some slight mods to the actuall support frame but technically speaking , you can pretty much put any guage on any bike if done the right way.. There saying on the link above that it was tried and not accomplished... well they gave up too easily... In less then a month or 2 ill have it finished on mine... Ill make sure i post pics of the final project.
jameson , get me some different pics of those gauges , they looked pretty sweet
