I recently bought a 1987 GL1200 w/ 49K. It was from a man who buys and sells older wings. I am handy with a wrench but not sure really where to start. At lower RPMs after it warms up the bike is missing/hesitating badly and then when the RPMS finally increase the bike suddenly comes to life and accelerates. I am on my second fill up (w/ seafoam) and have only gotten 50 miles from a 1/2 tank. Not sure if its just me but I swear I can see the gas gage drop while I am driving. I am going to start in my Clymer for some troubleshooting steps but would appreciate some better starting point than pulling the carbs. Good voltage but I am going to look what the voltage is doing when it is acting up. I don't know the bike well enough to get a feel for where the problem is coming from. Thank goodness I still have my GL500s to ride.

It's easy to make assumptions, but not always the best idea. Check everything you would for a basic tune-up. Plugs, fuel and air filters. You can learn an awful lot about the bike just by taking the time to do these things. If it was me, I think I would look for at least one, maybe all chokes are sticking. Should get a pretty decent picture and description in your manual, let us know if you need more help, and let us know what the problem was.
Got in a hour ride without any issues til the low rpm issue. It would struggle to accelerate then surge. It got steadily worse. I am gonna try again tomorrow and see if it has to do with getting warm. Thanks for response. I am going to spend time learning.

Just out of interest, you might want to hook a voltmeter up to your battery and watch the voltage at idle, then as you increase RPM's. Low voltage can cause poor spark at low RPM's if the stator isn't putting out enough power.
