Did some upgrades to our aclander 150atv today. I took the stock variator off and stock weights out. Put the new prodigy variator in and dr pulley 10g sliders in. The prodigy variator is much bigger then stock the sliders are lighter. The slider last longer then rollers. The end result more bottom end and more top end with the new slider variator combo. Just amazing how much of a change. Tomorrow is the red neck uni airfilter mod and new pipe and rejet, also a remapped cdi iridium plug and coil. Next week is the clutch spring 1500rpm as it is on order. We have done some of these mods to our buggy that also has the gy6 amazing. These 150cc motors take the upgrades well.
