One thing that I just noticed but your bike has an 85/86 swing arm on it. but your frame looks to have been modified to fit the 87+ motor that is in it. Could you take a picture or two of the two bars that come from the upper frame to the lower that are beside the combustion chamber as it comes out of you cylinder? I'm going to be doing the same thing and am curious as to how yours was done. BTW I'm just a little south of Salem.
