Fireblade carb repair kit?
Mark G - 30/12/08 at 04:43 PM
Following on from my fueling troubles, I have managed to get my fuel pump working now. But now I have fuel getting to my carbs, I find that the carbs
are leaking fuel.
I was going to strip the carbs and do a complete rebuild with new gaskets, seals and washers but after going to Fowlers today and finding that just
for parts it'd cost £130!! 
I think the fuel is coming from the union on the carbs where the fuel hose connects to. I can just get these seals at a cost of £15.
Before I buy, does anyone know of anywhere I can get an aftermarket repair kit for these carbs as I can't really afford £130 just for some
gaskets. Its cheaper to buy another set of carbs off egay.
Thanks
Mark.

Call Andy from AB, bet he can sort it for you. he knows them inside out and back to front.

Where are they leaking from? A sticking float valve can cause fuel to leak out and may just need a clean.

Great link, I've bookmarked them but unfortunately it looks like they don't do carbs.

Can he get cheap parts too?

It looks like they're leaking from the fuel feed to carb #1
I've arrowed to it below.

Have you tried David Silver spares? Good service for me in the past and they sell pretty much all the little bits and pieces....
Can't remember what the US $:£ exchange rate is like but Bikebandit are another place to buy bits from. Certainly 6 months ago when the exchange
rate was good it was an excellent way of saving money and they sent out the bits airmail (ie only a few days extra compared to UK:UK).

If they are the same as my Mikunis that'll just be an 'o' ring so should be easy to get hold of for a few pence.
Is the fuel feed an alloy link pipe between each carb?

no, its plastic. I'd have thought it'd be a few pence too but it seems honda want £7 for 2!

As Stu says - if they're similar to a Keihin carb, then there will be an o-ring on the T-piece. Here's mine (with the extended one I
made):
The o-ring cost me 10p - except I was embarrassed to spend so little after wasting the man's time in Pirtek (supplier of hydraulic/pneumatic tool
fittings). I think I bought 10!
It's worth splitting the carbs to see if it's as simple as that (not a hard job, if you pay attention to what goes where as you take it
apart).

I think thats what I'll have to do.
I'll just be sure to take photo's of everything as it comes apart.
I'm slightly paranoid about the carbs anyway as the screws all look like they've been tampered with previously so I don't know if
someone's fiddled with them in the past and not put them back together properly.
Think I may have to have a closer inspection, fingers crossed I'll only have to replace the o rings.

I seperated all of my carbs today and tomorow I could do with getting some rubber 'o' rings. Does anyone know where I may be able to get
some in the Bristol area? I need 10 in total, 3 different sizes.

Keihin and Mikuni carb screws are notoriously made of sh***metal, which is why they look 'tampered' with. 
It's a good idea to replace the float bowl and vacuum covers with good quality allen head bolts while you have them out. Otherwise you may find
yourself drilling out a stripped phillips head in the future!
Typically the float bowl gaskets and internal o-rings will perish from age and exposure to petrol. I know Honda take the wee a bit with parts
prices, but would suggest getting "pattern" o rings and buying the Honda-supplied float bowl gaskets. If this is an older engine,
it's a good idea to take the carbs apart completely and get them squeaky clean. Carbs from a broken bike will often sit around, so the fuel
evaporates and leaves varnish in the float chamber, jets etc. That can block jets and cause the float to stick.
