"77 cb 550 carbs
« on: June 28, 2006, 02:31:17 PM »
Silly question i'm sure.....
the float height setting on the '77 550 is  about 14.5mm

is that to the bottom of the float?    the farthest point from the body ?

that is how the others are set. just looks strange to me

thanks     jeff

Sure sounds odd to me...I just set the float heigth on my 72 CB500 at 22mm...

Check your manual...that doesn't sound right...

And here's a pictorial for a 750 rebuild w/float adjustment; 550/500 is similar...

14.5 mm is correct for the X46A carbs found on the 77 CB550K.

Measure from the float bowl mount flange to the lowest part of the float while the needle valve is still seated.

That must be a completely different casting from my 500/550 carbs...I don't think I could bend the tab enough to let the float in my 627A's sit that low...(or is it sit that high??)...   ::)

Edit: Just checked the Fiche; the 77 is a completely different carb from those in my junk carb collection. Latest carb I had was an 087A, which still had the basic 627A casting...from a 76 550...

Well, I'm glad I looked...Now I know what to stay away from...   ;)

My local salvage yard had two or three aisles of shelves with racks of carbs only on them...all old, dusty, dirty, crappy looking...the whole place was like that...collapsed roofs and floors; literally a thousand old Jap bikes laying in heaps; stripped; rusty; crusted dirt...I was looking for handlebars, but I spent an hour and a half looking around with the owner...in late 1800's buildings, also falling apart...no electricity, just the sunlight through the holes in the roof, and a small flashlite the owner had...four big old stone buildings, lofts, cellers, bikes in every square inch of space...and not a decent looking machine among them...abandoned for 20-30 years...some still had plates on them...

A motorcycle graveyard...so sad...   :'(
