Yaa, I deff hear what your saying. I dont really know how long it takes to adjust a timing key so its a lot of cash for sure$$. It works great though, I can say that for sure. I really never switch it much anymore. Once I found the setting I liked. It would be more worth the money if at this point I used a laptop to dial in curves and what not. Just a lot of work to go out and ride. I have a port and polish 40 over. Its just a head,carb's and a cheetah from hear.
