SC33 leaking carburetors

Hey, i've been transforming my 98 blade to more aggressive looking and i have now encountered my first real problem with this project.

I assembled the bike and got it running after 5 months within 5 seconds of starting. After a minute i noticed a fuel leak that was coming from somewhere near the carbs.

I removed the carbs and did some leak testing with water and I could clearly see the water leaking from the unions between inlet T sections and the carb bodies. When I move the inlet hose so the T unions move too they all leak.

do i have to separate the carbs to change the o rings inside or is there something else i can do?

Just for clarification, the inlet hose is connected to a t section, and both of these hoses are connected to another set of T sections that go inside the carb bodies.

Re: SC33 leaking carburetors

The union between the brown T section and the carb body is the leakage point.

SC33 leaking carburetors

If your talking about the unions between each carby the answer is yes.
Each Union has Orings. There is a set of long bolts holding the 4 carbs together. A good work shop manual will show you how to dismantle. If your handy with the tools you should be ok.

Re: SC33 leaking carburetors

each union has 2 o-rings. had the EXACT same thing this year when i first went out to ride. thought it was a stuck float, took everything apart and cleaned it all up put it back together and still leaking. a regular carb rebuild kit DOES NOT come with the o-rings you need to replace for that T fitting, fyi. i got new o-rings at ACE and put em in, all is right in the world again.

Re: SC33 leaking carburetors

Hey everybody and thanks for the answers.

I searched and searched the internet honda dealers + ebay + couple of local honda dealers and the cheapest option was 50 from ebay, 40 of that was postage.

I read a couple of threads about the same problem and some people got the O-rings swollen back by fuel. I had nothing to lose so I hanged a small maintenance fuel tank from the ceiling and left the carburetors on the floor under fuel pressure for three days.

After an hour the unions only leaked when I moved the fuel hose. Now after three days the O-rings hold fuel and I cannot get them to leak no matter how I move the fuel hose.

Lucky me, thanks guys
