Carb Synchronization After ANY Work?

Postby BirdDogICT » Sat Jul 10, 2010 9:29 pm



I recently removed carbs due to heavy rust and varnish in the fuel tank that completely clogged the fuel filter. I couldn't believe the amount of rust, since I always kept the tank full, and it was clean as a whistle after I boiled it out with acid a year ago. I had the tank cleaned at a local radiator shop, removed the pickup screens (they were damaged) and coated it with Red-Kote. I'm getting great flow of clean gas now.

Some of the gunk made it past the fuel filter, so I removed the carbs, split the air chamber, and then blew out the main jets and idle circuits of each carb with spray cleaner. The only obvious problem I found was a small amount of rust in each fuel bowl, everything else loooked pretty clean. I didn't change any of the settings, as they were locked with paint when Pistol Pete rebuilt the carbs last year.

After reassembling the carbs, the bike runs great on the highway, but doesn't idle very well, fluctuating from 1200 to 2000, and engine dies below 1000 when warmed up. When idling, the carbs make faint popping sounds as the idle changes. I'm running Sea Foam to try to clean the idle circuits, but should I perform a carb synchronization?

Absolutely, after that amount of work on the carbs, a carb sync is definitely due.

Thought so...have been looking for a good reason to buy a set of vacuum gauges. The SyncPro Carburetor Tuner looks like a decent, simple tool.
