If the overflow tube is cracked split it can be replaced but it's easier to sleeve it on the outside with some bass tube then solder it in place. If you've got an radio control model shop near you they are a treasure trove for little odds and sods like brass tube, piano wire to make springs, small t...

Another thought. With the bowl off fill it with fuel and see if level drops. If it does then the overflow tube has a crack.
Which means when the level drops from dumping fuel from the crack, it refills and then repeats again etc etc.

Sounds like the float is sticking on the bowl side. When bowl off works fine, when bowl on overflows. Can only be a clearance issue between bowl and float.

Thanks Gents, one of those bikes that gets played with every close season. It's never quite the same 2 years running. Sometimes for the better, sometimes for the worse so gets swopped back immediately

Hi Warren, for such rare / seldom seen for sale items it's a case of how much someones prepared to pay / how badly they want them ! Especially for an early Zed - there'll probably never be another set come up for sale ! ...... Just watch this Forum ~ "For Sale" section in the next couple ...

Roughly, What would you think they are worth on there own complete as a guide? Cheers I sold a proj...

Or T or vent.

Good on you Gray, makes all the effort and hassle a dim and distant memory. Just snagging to do now? Every build has a few niggles to sort.

Look like BS34's off a 1000 J

Hopefully sorted now. Thanks to Graham (Maunders).

Messing about with some old clocks but need a clock crimp ring.
I know they are available from cb750 site but don't need a pair and don't need new, just better than the totally butchered beyond use one that I have.

Google the part number, loads on ebay. Its a part used on many models of the era.

Depends how good the surface they are bolting too is, scratches, pitted etc. A smear of rtv won't hurt either way.
