Carb Problems

[Jumbo]

I have been helping one of the SW boys down here re assemble a z1000 he bought. Today we got the carbs connected up with petrol but had leaks from the "T" pieces where the fuel hose comes into the carbs. Both sides. I see on Z Power they are £16 each. Also on US Ebay there seems to be a different type which uses O rings. Ours are a rubber coated steel T.

Is there any magic fix or just replace with new ??

hi jumbo, you say "reassemble" so have the carbs been dry for a while ? its not unknown for the rubber to dry out and leak. may well stop now that fuel has soaked them.

I have managed to seal a weeping one by assembling with a smear of threebond gasket sealer.

Also, before you buy any replacements, strip the carbs apart and check the hole in the carb body, I've seen them badly worn such that even a new tee pipe won't seal perfectly.

hope this helps .

Jumbo, those leaking tee-pieces are a common problem.
I replace those originals with the aluminium tee-pieces (with the two o-rings).
I have found them a great improvement on the moulded type and seem to overcome any wear or damage to the holes, where these fit in the carb.

You can seal them up quite easily by adding the correct size o-ring, but new would be better.

Steven, I thought like you and looked at just slipping the correct size o-seal between the two moulded "bumps" on the original tee-pieces. They just don't work, as the o-ring has to be so thin, I thought, maybe the o-ring in the brake retaining bolts would be thin enough to fit? I have even tried putting a groove in the originals to take an o-ring.... Not much luck, as the moulding rubber is very thin on the tee-piece shank.

I have heard recently of neatly cutting some teflon tape, the fuel resistant type (brown.. I think!). It worked, however, it can look untidy!.

Importnt to use "O"-rings that are petrol resistant

Garn, your right the o-ring has to be quite thin, but they do work as I did it on my Z1000 and they where fuel tight, I still changed them though once I'd saved up for new ones.

Thanks for your replies, we had bought some small O rings and I am told from Keith (famous for the head to head wheel spin at the 2011 SW) the carbs are now tight and he has even had a run out of the bike !!

It will not start on the starter yet but it looks like there are a few electrical connections to check.

Unfortunately the bike will probably end up on Ebay, but it isn't a bad bike.
