Trust me, I have the original factory shop manual, a Clymer manual and a copy of the original owners manual. I am capable of doing what is left but since I do not have too much history on the bike I wanted someone familiar with them to have a look-see at it. With the carb re-build, Dyna S ignition, etc. I have installed/done myself I have a solid starting point for dialing it in. I have ridden the bike for a length of time and it is performing well with no hiccups at this point. The valve adjustment requires bucket shims and a few special tools. At this point, since I wanted the bike looked over, it would be cheaper to have a specialist do it than myself. Eventually I will order a shim kit from Bike Bandit and the required tools to do it myself. It really is pretty strait-forward. I think I will be using Dave Page of Page Racing in Norwood off Montomery Rd.
