Z650 fuel linkage O rings

[mattc]

kawasaki never made them with a seperate o ring fitted it was moulded to have the same effect as an o ring someone has probably fitted suzuki gs750b fittings that have seperate o rings & are available to buy seperate & are the same size as the kawasaki

Thanks for the info. The bike I have started life as a KZ and must have been imported from the US at some point. Don't suppose you know the part numbers for the Suzi O rings or who might sell them? The CMS website shows them on the diag but the part detail section is missing for some reason. Cheerss

I found the Suzi part number as 13374-73000 Any idea where to get them? Thanks

i worked at cradley for over thirty years as a mechanic & have stripped many of these carbs & have never seen them with removable o rings if they had removable o rings they would be shown in the parts diagrams or parts microfiche. contact dave marsden at z power if you want more confirmation gs 750b

Not getting anal about it just ensuring the thread has accurate info. I don't need to contact Dave, I KNOW from all the B1's I have worked on and restored. From the three B1's in this thread the owners have found all three to have O Rings.
From my 1976 Kawasaki workshop manual. As I said, B1's definatley had O rings, later models did not.

Cmsnl are known to get it wrong occasionally. Even the pic posted is not correct for non o ring 650 coulplings. 650 non o ring couplings didn't have ridged rubber sleeves. They were solid "plastic" of some sort with two rigdes each side to emulate o rings.
The pic I posted was from a Kawasaki manual who had the correct parts and info to hand as they were the manufacturers not third party parts suppliers.
Both my bikes have identicle to the pic I posted.

I'm taking an interest in this thread - the joining pipes between the carbs on my Z1A seem to turn a little too easily - I haven't tried putting petrol in the carbs yet, but I do worry that it will pour out of these connectors. Like the Z650, the Z1A parts book doesn't show separate O rings.

Maybe they'll swell up with fuel, or were never a very tight fit, I've still to find out.

Yup Warren, the fuel linkage pieces I have with O rings are identicle to the one in the Kwak manual picture for the B1. Matt

I took these out of a 650 B3 two years ago Paul

[warren3200gt]

Keith, were they 24's or 22's can you recall? Both of mine are 24's. Just wondering if 22's are the same? I cant imagine mikuni would have changed anything other than throat size between the two sets.

That's them exactly....except my O rings were quite distorted with age. Once you take carbs apart and disturb them they are bound to leak..

this is whats fitted to the suzuki gs750 & gs1000 part no 1368545040

[warren3200gt]

Think they may have mixed their pics up? Wouldn't know as never worked on a gs.
