Monkey Motor!
 

to all u ZZ owners this is a must have!!!! i luv this motor!!! , good torque , good speed!! and good handling, mayb im just really excited about this motor cuz i was always using a green one. but either way this motor is the best i luv it! but it took 2 weeks to get to my house i dunno why :(, all zz owners get this or get a better motor. thank u dks!!! and the pplz who said that higher than a 2.6 wont work for zz well they where wrong. gonna play with my zz! peaceout

sorta
 

well actually, nothing above 2.6 does work with the Zips, except the guys at DKS make a specially crafted motor specifically for ZZs without mods. Ex. try putting a Bit or LXX 2.6+ in your ZZ and see what happens

what is this monkey motor? or DKS or whatever

here this will explain
