I have two T140s sitting in my garage...1978 & 1975. they have identical center stands and appear to bolt up to the same spot on the frame. On the 75 it raises the rear wheel about one finger off the pavement. On the 78 I can put all 4 fingers + under the rear wheel. I realize the front wheel is the one elevated etc.... So what is the difference? Nothing is obvious. Could I cut a section out of the stand and weld in a supporting piece? I think it is cast steel. Weld mild steel to it?
