Marty, I would just make it longer and follow the path of the blue idiot-light wire. Either wrap it with good vinyl tape or use some small split-loom. I tried to hide most of the wiring on my engine but admit I took a shortcut with my temp sender wires, they are not pretty!
Jack, a few of us have made a hexbar mod of our own. It started on Spyderclub with a couple of us hacking up our CB Performance linkage. I am not sure exactly how to go about it on the linkage most Speedsters seem to have with the nylon bushings. Do a search on Spyderclub.com for "Bye bye hexbar blues" and a long thread should come up. I can try to help you, email me some closeups of your linkage, as a whole overview, and some closeups of each side from a few angles. Or post it all in a thread on here. I changed mine over 10K miles ago, and haven't had to touch them since!
As far as Weber tuning, no problem Marty. I would be happy to show anyone the bits I know at Carlisle next year. I will add, it would probably be a lot easier to demonstrate on a Spyder, as it is such a PIA to reach the adjustments in a Speedster. Whoever designed that system likes to torture people! I mean, why not turn the carbs around so the adjustments are toward the inside like my Spyder? It especially sucks to pull out an idle jet, ask Kelly(his car), Musbjim, Lenny and Corey how we know that one!
