spits and sputters

Postby blackbeauty » Sun Jul 14, 2013 12:20 pm



I have a 1980 GL1100, I have a question on syncing the carbs. I bought the gauges to do it right, I adjusted the valves and hooked up the gauges adjusted so that all gauges were the same. My question is can they be synced wrong. Before I did the sync I was getting 42 mpg's and now I get 38 and at 5500 and above it falls flat on its face. someone told me to open thee screws all the way and then turn them half turn and tighten the nut down. I have not done this wanting to find out what everyone on here thinks.

The first thing for you to consider in your troubleshooting is that adjusting the sync of the carbs effects the idle circuits only. If this started after you did your valve adj. and sync then you should go back and double check anything you have done. Including the valves. What type gauges are you using. If they are analog dial type gauges did you calibrate them to insure they read the same. Hook all 4 gauges up to the same carb one at a time and adjust for equal reading.

Yes they are analog gauges and I did check each gauge before hooking them up to sync. On the valve adjust I think I only had to adjust 1 valve all the rest were in spec.
