It was kind of the answer to the question nobody asked..
I am asking because my trike has a gas pedal and the bell crank system I made is out 1/16 in over full travel . A single carb would be simpler.

pressureanglThis thread is making my head swim lolI think I has a sickness. Somehow I just can't countenance the notion of less than one hole per cylinder.The Norton guys are always having the same conversation, but I don't think anybody there would allow somebody to show up with water pipe as a manifold. Guzzi people are the most curious community I've ever been part of. I can't understand "Why anybody would want more than ONE CARB. on anything between 1 and 4 cylinders anyway , CAN'T BUT ONE CYLINDER AT A TIME SUCK ON IT in a 4 stroke engine" ??? Four cylinders , Four cycle , One carb = smooth constant flow -- Smooth is Good for flowing things ! Those up-draft carbs are wonderful fuel savers !
Never ridden a single carb Guzzi or a Quota or Vt with a single throttle body, buy have ridden single carb Triumphs and truth be, I like their "ride feel" better than the twin carbs. As an aside, perhaps a Quota manifold could be adapted / modified for a carb if you're curiosity overwhelms you. Probably better than building an ornithopter during those long cold months in the nice heated garage.
Any one have a sonny angle manifold for sale?
Sonny and Chris’s last name was Angel, as in winged and white.The first Guzzi I ever rode had one of those asymmetric manifolds, it ran poorly and Sonny himself converted it back to twin carbs.Piaggio seems to have done a pretty good job implementing a single throttle body, and it would be interesting to figure out why it works better than the Todero era Quota setup.
Interesting timing. Just had short conversation with Don Angel, Sonny's brother about the single mani. Interesting.Tom
That "Triumph" manifold above looks like it came off a toilet...Looks too long to clear the engine casting? I tune old Triumphs, there's a lot of debate on single VS dual carb..When properly tuned, the dual carb is better above 3000 rpm...in my opinion.......Those long intake runners on a Guzzi single carb manifolds may not get warm enough to help in fuel vaporizion in cooler weather...
