Carb fuel leak.
After the last two days out, I've noticed a small smell of fuel in my garage after putting my bike away.
Whipped the airbox off and had a feel round the carbs, the area which has fuel on it is opposite the carb cover, see red circled below. Sorry for the small pic, I took it off an ebay auction. What is this part called? Will a simple strip and rebuild of carbs sort it, or is there a type of seal there that will need replacing? I want to nip it in the bud asap before it gets any worse, right now it's only a slight drip of fuel. |

Re: Carb fuel leak.
Gasket 14? Should be the float bowl gasket?
http://www.powersportsplus.com/image...08/08/0010.png You might be able to temporarily seal it with some black silicone sealent (the one that is heat and fuel safe) the SV carbs and float bowls are at an angle due to the V twin layout so I guess that the gasket has just got old and has started leaking, you might even be able to make your own with some gasket material.

Re: Carb fuel leak.
I've never seen a properly fitted 'O' ring there leak*, the float bowl could be loose, or the same could be true of the drain screw.
Need a more specific picture or description of fault to be sure. *It could have been fitted arsewise or course, it could be pinched or not fitted in the groove correctly

It could also be the black pipe ? As that is what feeds the carb with fuel. Check the clip and make sure the pipe is not ripped or broken.
If the gasket leaked woudnt the bike run like a dog ???

Re: Carb fuel leak.
If its the float bowl gasket than it would just keep pumping fuel in to bowl as it drops below the required level but yeah I would check the fuel pipe and clamp as well, the clips are fairly exposed so can corrode.

Re: Carb fuel leak.
Fuel line is fine, I reseated it earlier to check. It is directly below the fuel line for the rear carb if anyone is familiar with it. I'll try to find a larger pic on google.
The bike has never had a problem until two days ago, you can smell it after a ride when my bike is in my garage approx 30 mins after I get home. It's a tiny leak right now, talking about 2 drops of fuel. Yes m1tch it looks in a similar position to the float bowl gasket! I thought it might have been a gasket of some sort. I work during the day until 5 but I'll try to strip them down in the next few days. Can you buy a float bowl gasket from any suzuki dealer - a couple of pence I imagine? The bike is also running fine too Last edited by Scythe92; 03-09-12 at 09:48 PM. |

Re: Carb fuel leak.

Re: Carb fuel leak.
I've found a carb rebuild kit on wemoto for £20, containing the gasket, o-rings and floats etc. Bit annoying because I only need a gasket if diagnosis is correct.

Re: Carb fuel leak.
Guessing can be expensive, get it apart and find out exactly what is leaking.
