If there are crossover tubes then you for sure have 1100 carbs. I just replace those seals with nitrile o'rings from a set that I got from Harbor Freight. I don't remember the size but they were included in the set. I think the oring set cost about 6 bucks. I hope you realize you will have to separate each carb from the plenum and from each other in order to replace those seals..... As for sealing externally ??? I doubt you will have success. Might as well bite the bullit.

That would be about as likely as saving the titanic with duct tape.

+1 on biting the bullit. While you're at it anyway, I'd just do the job properly: with the carbs apart, you might as well inspect them internally and put in ethanol-resistant seals everywhere. Does Randakk also sell those for the 1100? A job done properly will give you peace of mind.

First off: I have no commercial interest in this whatsoever. That being said, "Randakk" is Randall Washington. He is a goldwing specialist and sells nice replacement parts for early goldwings. Just google him. It isn't necessarily cheap, but in my experience if you buy cheap imitation parts you often end up doing a job more than once.

There is only 1 accelerator pump, on #3 carb. Those other things are air cut off valves. Be careful and use a good #3 phillips bit on those big screws. Randakks kits are the best but costly. Less than you would spend on genuine Honda parts though for all that is in them.
