K7 Fuel leak-injector area - SV650.org

So I decided I wanted to take the SV out after not riding it since the oil change in July. Fired it up to warm while I put my gear on. I spotted a small patch appearing on the floor and smelt that it was petrol. Shut it off and had a look. From what I can see it seems to be coming from the front most part of the link pipe on the fuel injector rail. There are no leaks when the engine is off.

I spoke to Orwells who said it should just be a case of replacing the pipe. The mechanic suggested trying a jubilee clip in case it has just come loose to nip it up a bit. I assume I will need to remove the injectors to replace it, but will this mean a new seal kit? Any advice on the best repair for this?

stick the tank on and have a look when bike is running.

I checked it with the tank on before stripping it down. Only place I can see it could have come from.

Bibio · 21-09-13, 01:18 PM

could have?... was this without the airbox on?

In the pic there is a braided cable going through the frame below the pipe. The drip of fuel was hanging off that frame but on the nearside, as if it had run along the rail past the brown connector and down the frame,then dripped between the cylinders and down the case. It was on it's stand at the time. By the time I got it stripped down the fuel had evaporated.

this is why i'm saying run the bike again with the tank back on. this will show you where its coming from. if you make sure that everything is dry and then dust with talcum powder it will show you where the leak is from.

you might even get away with just priming the system rather than running the bike.

Thanks, I will be looking at this later in the week as the bike isn't to hand. Can the hose be replaced easy enough or is it going the be a throttle body strip down?

Bibio · 21-09-13, 01:36 PM

hose is easy enough if you have nail pulling pliers to cut the old rings off.

Kenzie · 21-09-13, 04:04 PM

Might have to buy some. If I cut this hose off will there be much spillage or will the system not flow if the pump isn't running? Also, how do I prime it after?
Are these what you mean?

yes those are the ones.

make sure the tank is removed. there will be a small amount of petrol (what ever is in the system). no it should self prime.
