GS650G carb cleaning

[duaneage]

I have a 1981 GS650G with 12K miles on it. I am considering cleaning the carbs and replacing the float seats as both a preventative measure and to improve driveability. I have seen a $12.00 per carb kit that includes a few gaskets and the needle assembly, is this all that is needed to rebuild? Could I use an inexpensive mercury meter to resync the carbs after I am done or do I need to get a shop to use a more accurate gauge?

The bike runs pretty well so I am hesitant to clean the carbs. Should I just leave it alone or maybe take it to a professional?

The pictural on rebuilding carbs looks easy, are they GS650 carbs in the pictures?

If its running well and not leaking any gas, I would just ride it.

I'm not sure if they are 650, however, when I rebuilt mine everything appeared exactly the same.

If the bike is running good and the carbs show no visible problem, I would leave it alone. With only 12,000 miles, the (most likely) original float needle valves should not be worn yet. If you do have any leaking/overflowing of fuel out the overflow line(s) it would be most likely varnish or some dirt interfering with the valves ability to seat or a sticking float(s).
Motion Pro makes a simple but good working mercury vacuum tool. About $35 last I looked. Easy to set up and use. There are others that work fine too.

If the outsides of your carbs look the same then they are the same on the inside. The 79 (or 80?) and earlier carbs look really different.
