I have a shadow X5 with the original 9" coil that has a short in it, but can be fixed, and also a new 9" coil that I bought and used only twice. The center rod on the machine needs to be replaced. The plastic tightening nuckle is broke. So the shaft wiggles. I put tape on the nuckle which held but with use it starts to wiggle after a while. The machine works great and I just paid 140.00 for the new coil that I found that a dealer still had inventory. I will sell shipped to the lower 48 states for the first 325.00. The price is firm and I dont want to trade unless you have a like new CZ21 or a Garretts AP Pro I think its called. I will nayurally add money to the deal. Thanks for looking and if you would like to talk give me a call at 715-851-8733. Thanks Jack
