This video demonstrates the procedure to synchronize a carburetor on a 1977 Honda CB550. It is really important, especially for bikes of this vintage, to synchronize your carbs at the beginning of every riding season or after any repair or adjustment to the carbs. This bike still needs some work to be road ready, but it has a lot of potential and is super cafe racer cool. If you are attempting to do this procedure yourself and have any questions before you start, feel free to let me know. That's the good thing about Youtube, FREE INFORMATION FOR ALL!!!!!


EDIT: Here are a few edits I would like to make to this video after watching it a couple of times.
1. Make sure your carb synch comes after everything else in a normal tune up. This includes Valve clearances, cam chain tension, spark plug gap/cleaning, point gap, ignition timing, air filter cleaning/replacement, and all the air bleed screw settings should be checked.
2. Engine speed for a carb synch should be around 1500rpms if possible.
3. The adjuster screw lockdown nuts should always be re-tightened after adjustment (I forgot to show it)
