I thought Z1 was suppose to be a REALLY good Z shop and knew what they were doing. If they knew there motors sucked why keep selling them and loosing more and more customers? Im sorry to hear the bad news man I really hope you reconsider selling the Z and just getting it right again and go back to enjoying it. On that note I would REALLY like to see Z1 respond to this thread and explain why they continue to build crappy motors?
