I like Webers in general. They improve much with proper jetting. They are as precise as motorcycle carbs, which is pretty darn good.
Whatsit doing?
Around town it seems fine, albeit extremely thirsty - I haven't tracked mpg real close but it under 10. On the 40s only run I fueled up before leaving and made it back on fumes pretty much.
On the run it seemed fine until we approached the top of Kingston peak. It died going up the semi steep approach at the top and didn't want to keep running. On the way down the other side it would die if I pushed in the clutch and then just above Alice to all the way past Idaho Springs it was back firing. Once over Floyd Hill it returned to its "normal" self.
Around town what I notice most is an occassional desire to "bog down" if I floor the gas in 3rd or 4th gear and an occasional desire to not want to run (i.e. lose power) when climbing an incline and trying to add throttle.
I chatted with Jim C about a rebuild but he won't touch Webers for 40s - Webers for other vehicles he will rebuild no problem but not for the 40s. My next step was to buy a Weber manual, new higher elevation jets and whatever else would come in a rebuild kit, and muck my way through a rebuild. My goal is to have the 40 ready for CM09
