  1. So when the warning light comes on, I still have approximately 1.3 gallons left?
  2. The previous owner gave me his Topeka Powersports receipt. They charged him for the diaphragm assemblies and one hour of labor to install them. I would think the technician would sync the carbs, because the service writer wrote the work order as poor fuel mileage. Would syncing the carbs show up as a separate line item on the receipt? Is one hour enough time to install the diaphragm assemblies and sync the carbs?
  3. Installed two new plugs in the front cylinders, 4 more oz. of Sea Foam. Performed the 30 sec. run test. Front two cylinders might have been a little warmer (my pyrometer fingers). Fuel gauge says half a tank (three bars)(it has to be a 4 gallon tank) Trip odometer is on 70. I'm gaining on the mpg. When I get real ambitious, I'll tweak on the slide needles.
  4. Thread the needle in, lean. Thread the needle out, rich?
  5. Approximately 4 oz. of Sea Foam went into approx. 3.5 gallons of gasoline, and my mileage jumped to 30 mpg. Next, I'm trying more Sea Foam and two new front cylinder plugs. I too have installed bad, "new plugs". Keep it Simple, Stupid. If I can get it too 35 mpg, I'll be happy.
  6. I am assuming you guys are talking about the needle jet screw? In the ignition system chapter, they suggest testing the spark with an Electro Tester. On an automobile, the spark tester makes the coil jump 1/4" gap. In the mean time I'll try some Sea Foam (being how I have some)
  7. All four carburetor slides are sliding. Going to concentrate on the ignition system, after I research the carbs (float circuit???) Seven circuits common to all carburetors. Choke, Float, Idle, part throttle, full throttle, full throttle full power and acceleration.
  8. 30 second run test, Rear cylinders hot, front cylinders warm. I pulled the front two plugs, one had raw gas on the threads. Even my wife said, "did you check the air filter?" A dirty air filter would cause all four to be flooded??? I will try removing the air filter and check the slides
  9. would you recommend clymer repair manuals? I'm not sure how to remove the the lower leg fairings to do the exhaust pipe touch or pull the plugs. there is no lack of power to be running on three cylinders. If the power I have is three cylinders, if I get #4 back, it should do a wheelie with the twist of the throttle.lol
  10. 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? Gilbert
