alright sorry to do this to you guys cuz i know how the zr580 topic goes around here but yes i was stupid enough to buy one last year well long story short the motor blew twice last season and i dont want to run that motor next year. i was thinking about doing a motor swap...do you guys think it would be horrible to plant a zr 600 motor in it? how available are these motors and are they rediculously expensive? lemme know what you would do? thanks for your time...!!
