larrydr Posted March 28, 2022 Share #1 Posted March 28, 2022 I am running some Carb problems on my 83 1200 , and rather than put a large amount of cash into the old carbs I would make a single Carb manifold ...The difficulty I see is getting the fuel jet sizes right ...I have built manifolds before , it does take some time to the fit right ... I have a Carb from a Chevy S10 4 cylinder truck ...The local muffler shop will bend me short 90 degree tubes ... Please someone tell that I am crazy and that I need to see my doctor ..

campfire12 Posted March 28, 2022 Share #2 Posted March 28, 2022 Its been done before.There should be some threads on this site someware on the process. i thought they was useing vw carb but i might be wrong. I think throttle response was the big problem. 1 Link to comment Share on other sites More sharing options...
BlueSky Posted March 28, 2022 Share #3 Posted March 28, 2022 (edited) I think you can buy manifolds for this purpose. Try ebay. I just googled and there are some already made. https://www.google.com/search?q=yamaha+venture+4+carb+to+single+carb+manifold&rlz=1C1CHBF_enUS975US978&sourceid=chrome&ie=UTF-8 Edited March 28, 2022 by BlueSky 1 Link to comment Share on other sites More sharing options...
larrydr Posted March 29, 2022 Author Share #4 Posted March 29, 2022 @BlueSky,,@campfire12 ,, I know I can make manifold for about $75.00 ...The carb has secondary response system much like the GM Quadrajet carbs have that is used on the small block V8 engines Link to comment Share on other sites More sharing options...
