I got to use a drill and a mini-grinder and even a cuttin torch! The funny thing is now that it's all done the vibration that I had round about 35 and then again round about 65 now is from about 1 to about 30 then it kind of dies away. Ah well such is life. It's all done and seems to work pretty well as it seems to ride smoother. Gonna have to find some place to see what the hind end does flexy wise.
