carb part ID please :: DONE, THANKS!

[Anonymous]

OK, so it's not a GS part. Still, please help. I believe it's a set of Keihin 26 mm from a 76 CB550.



Look at the tubes pointed to by the yellow arrows. What are they? What should attach to them?

The fuel supply tubes are in the upper left corner of the picture. If they are meant to be open, why are they pointin up? Wouldn't that be inviting moisture to get sucked in?

But closer examination shows that you're probably right. I thought they entered next to the slides but it actually looks like they vent down into the bowls.

Done! Thanks for your help!

I too, think they are vent tubes. Put some hoses on them and run the hoses down the back of the motor by the swing arm, if possible. 8)

Thanks for the help. I got her running tonight. Actually I got her running last night (or was it the day before..?). Anyway, she's running better now, and loudly. Gonna tape up the mufflers for a bit of reprieve. She's overflowing in the bowls though, out the vent tubes. I think my custom cut-out bowl gaskets might be hanging up the floats. Hope not. But if not that then what?

A little sleuthing showed that she has parts from at least three bikes in her. The VIN on the frame is different from the engine, and both are "K" style VINs. The airbox and some other parts say "F" style on them. She ain't pretty and never will be, so she got named "The B****". Maybe "The Mongrel" or "The Mutt" would be more apt.

They are for the floatbowl venting lines. If you are running the stock air box, you should install the lines and route them where they'll stay clear.
If you are running pod filters, you should remove the lines so the bowls will vent easier, allowing the jets to draw fuel easier. This is necessary when the air intake increases due to pods.

Like I said, she's a mutt, so I don't know if it's quite a stock airbox but it's definitely not pods.
