I recently bought a 1983 Venture 1200. I only get 25-28 miles per gallon. the previous owner sent it to Topeka Powersports for poor fuel mileage. They installed new Diaphragm assemblies. Is this milelage typical? or is something wrong? I have talked to two other venture riders, one on a poker run, and one @ the truck stop, and apparently fuel milelage is low. On the Venture history page, it states the average fuel mileage @ 42.5 mpg, it states the capacity @ 5.3 gallons, the owners manual says 5 quarts. The warning light came on and I put 3.92 gallons in. Trying to decide if another carb overhaul is warranted this winter?
