Hey i am considering going from 121 ro 141 on my 1998 vmax xtc 700 and want to know all the mods i have to do besides extenisons of tunnel and rails and maybe drivers if i get a big paddle. Thanks and let me know
20 x 40 is popular with 9 tooth drivers, and 23 x 40 is popular with 8 tooth drivers. You will need 8 tooth drivers with a paddle. You likely have 22 x 39 or 21 x 39 in there right now, if you switch to 8 tooth drivers it will be pretty close.
You can likely find parts on here, or at www.SnoWest.com, or you can go with a kit from Hartman or Mountain Performance. You likely have 22 x 39 in there right now, if you switch to 8 tooth drivers it will be pretty close.
