Just so everyone knows, we have gotten more than one person questioning this frame. I think what most people fail to realize is that the left and right lower frame tubes are each one piece and I welded them to the existing frame myself. These tubes alone may have held up just fine. The cradle is plenty stout and I know how to weld. I don't have any tig or aluminum experience, but I have many, many hours behind the arc welder and especially the mig welding steel.
This is the frame prior to gusseting-
This is the picture that I think is confusing people-
Yes, there are ugly welds up top. Dan is not piecing together a bend or anything like that though. The picture is an odd angle and Dan didn't explain it well. The metal you see him working on is merely a gusset going over the existing one piece frame rail. Yes, the ugly welds are going to have to be ground and smoothed. If I had been able to make it to Dan's house this weekend (we had a snow storm and my 2wd truck couldn't move) the welds would have been pretty and they wouldn't have to be ground. I wasn't there, so we grind them. The strength is not compromised, just the look different. Let's not forget, this is a first-gen Tecate and they look like farm implements anyways. If any of you have ever looked at the factory frame welds on a Tecate, it only makes sense to assume the welders at Kawasaki more than likely got paid per-frame.
That being said, the progress we all see here is as new to me as it is to you all. After really looking at the pictures, the place that worries me is at the bottom of the gusset. I probably would have gusseted the top where the new metal meets the existing frame and that's it. I wouldn't have gusseted down the rails at all. I don't like how the gusset ends at the bend like that.
