I recently bought a 141in x 2" track for my stretched mxz 670. I'm installing 8 tooth drivers to fit it . This is basically the same setup as the 98 summit 670. Now the real Question. I need to rebuild my drive clutch. Ramps, pins, rollers the works. Should I install the original mxz parts or switch to 98 summit setup? If anyone has tried the switch one way or the other I'd appreciate the input. ???
