Has anyone changed the gears in their mach z? I have a friend that wants to try this. He wants a 1.76 ratio, 25 - 44 gearing. What results have you seen with gearing changes on the mach. Thanks

WE have been all they way through the whole chart with the mach, from 1.55 all the way to 2.0 to 1 and it really depends on what your doing. If you are full of picks or chisels and not spinning a 1.95 to 1 was real good but as far as trail riding or trail racing with carbide studs the stock gearing is pretty good. The 1.76 your buddy is shooting for really won't be noticeable unless you are running timers on a track.
