definately somethings amiss. the main fuel line hook is supposed to be attached to carb 1 not 4. the choke lever is supposed to be attached to carb 2 on the other side of the main fuel line...that is, if this is for a vmax ;-). The carbs themselves look like what i just got done messing with. Eh, so the PO reassembled them wrong. Shouldn't be a big deal to reassembled correctly, no?
The guy said they were Venture carbs. :ummm:
86 to 88 venture carbs are 35 mm and the venture had the choke lever on the handle bar with a cable running to the back side of the #1 carb and the choke linkage on the carbs is spring loaded.
I agree on the choke but here are the specs:
The earlier model 1200cc Venture was very well received, but still struggling in the marketplace against the Goldwing. For 1986, Yamaha made some changes. Capacity was increased to 1300cc for more power, luggage capacity was increased by 50%, it was fitted with electronically controlled anti-dive forks, and passenger accommodations were enhanced. Despite all the engine improvements and extra power, the new Royale could still pull 45mpg. Changes were kept to a minimum from 1986 until the end of the production run in 1993.
Here are the specifications that I have gathered on the '86-'93 at this time. Thanks to Russell Hicks for his help in compiling this information. Make and model Yamaha
