Topic: Any trick to removing cb400f carbs?

[zoo mob]

I need to pull mine off the bike I bought last fall and have not really touched since. Any trick to getting them off, I'm just worried about losing the sync etc. Thanks

There are no real tricks.  The procedure I use follows:  loosen the clamps on the rubber boots on either side of the carbs, loosen the clamp on the rubber boot which connects the outboard rubber plenum to the airbox, remove the cables to the throttle, turn of gas and remove fuel lines from the carbs, remove the air filter element,  pry out the oval metal pipe between the air filter box and the outboard rubber plenum (you will need a big screw driver to get the rubber seal off the air box), remove the drain line from the bottom of the outboard plenum, remove the outboard plenum, pry off the carburetors ( you will not change the carb sync as they are all still attached together). Job done.  To reinstall just do the procedure in reverse.  I have found the most difficult part is getting the oval rubber seal back on to the air filter box.  I use a two by four and a smaller board to leverage it in.

Good procedure.
You'll have to pry the carbs pretty hard if they haven't been off in a few decades. A piece of wood between the engine and carb mounting plate is good, working one side then the other. A bit of dielectric grease on the inside of the rubber spigots and on the carb nipples will make getting them back on (and off again) much easier. If the rubber has turned to stone then new spigots (carb insulators) are a good investment. These seem to be available, but around $30 each.

why are you taking them off?
if they need to be cleaned/adjusted, you should resync anyway.

Once fuel lines, throttle cable and airbox are diconnected, and the clamps are loostened. sit on your bike and heave away...rotating the bank of carbs up and down while pulling out of the engine boots.

Someone around here uses a tie down strap to hold the airbox back.  There's a picture of it in the thread if you find it....  I try to pull the carbs as evenly as possible straight back.

I really just want to pull the bowls and clean them out, too bad they switched to the screw type from the earlier snap-on style. Thanks for all of the tips.
