[QUOTE="Cyborg, post: 118494, member: 3426"] Both.... it’s been a long time in the making. Not just adapting oddball parts, but also spending lots of time making parts and then... although happy with the way the part turned out, it looks out of place when installed. Longer wheelbase than planned because the initial swingarm was shorter. It was made for eccentric adjusters and all was going well until I had a brain fart. Everything was strapped into the jig for a test fit and things lined up quite nicely so figured why not just go ahead and weld it. If I had been thinking, I would have welded it in stages. As one would expect the area that holds the eccentric adjusters warped slightly. That wouldn’t have been an issue if I had welded the arms separately. Then it would be a simple matter of bolting the arm into the mill and correcting the out of round. The welded assembly is to large to fit in the mill. I suppose it could be attached to the carriage of the lathe and bored that way. Things were dragging on so I grabbed a 650 BMW swingarm out of the dumpster and used that. It needed machining and welding, but was a quick fix. The Comet is still shorter than the V11, so should be fine. The other thing I found with the GT and 750S is that they seemed to be very forgiving. You could screw up steaming into a corner and make corrections that would cause other bikes of the era to try and spit you off. [/QUOTE]
