No Power

[Jack64]

Hi guys, I am new to your site, forum. Wonder if any one can help. Bought my 750 about two weeks ago. was a non-runner. I sorted out couple of things, including the carbs. Dismantled, cleaned and then bench synced them. Bike was running fine. Then I vacuum synced the carbs. Now, I have a splutter when I accelerate. I can redline the bike standing still. Replaced the sparkplugs. The old ones were black. HELP

What year? So your bike was running well and then you vacuum synced them and now it has problems?

Hi Travis, thank you for replying. The bike is a 1982 model. Yes, was running great, and then I was told it needed the carbs synced. Now, as I mentioned, she splutters.

Wow that looks clean! Who told you the carbs needed to be synced? I mean what symptoms was it showing that lead them to believe that? What procedure did you follow to synchronize them?
