I bought all my parts from the guys at Hk and after I had someone else put them on, I didnt feel right about somthing. Now after getting my Ninja back after so many years, Hans and Rick are making sure it is running right. I dont have a lot of money because I have cancer and the meds are very expensive. I trust that they will take care of me without charging me an arm and a leg. I will always use these guys for all my work.
