Paul, thanks for the comments. I'm now being tortured by all the little details that will prevent me from getting this bike on the road.
The aftermarket 3 into 1 is a Alphabet exhaust. I have the original box, with the stock exhaust stored in it.
When I rebuilt the carbs about 2+ years ago, before this went on hold, I followed Triumph's original instructions about adjusting for altitude, and went DOWN in main jet size. I hadn't thought about the change in exhaust, nor had the PO who did the work with me. It may be a mistake. He also had switched to pods, rather than the stock air filter. I may have to rework the jets back to richer.
The bike was originally set up for Tucson, which is pretty low compared to Santa Fe and most of NM.
