2022 FTR Fuel Leak

[Dbowles24]

Howdy all! New to the forum with a 2022 FTR S. The bike has been almost perfect so far and I really appreciate all the help y'all give on these forums. I've been noticing a fair bit of fuel (possibly mixed with oil) under my bike after it's been parked in the garage. It appears to be coming out of the overflow tub next to the radiator overflow on the left side of the bike. When I first catch it, it is 100 percent fuel. If I come out later, it almost smells like fuel mixed with oil? Tracing that line up, it appears to come to a t-fitting that splits into the fuel tank and the airbox (could be wrong). I do not have the evap system if that makes a difference. Lastly, this issue occurs regardless of if the tank is full or almost empty. Does this bike have a fuel vent or something that could be plugged up causing too much pressure?

That’s most likely the vent line you’re referring to. Don’t plug it. Did you fuel up before you put her away for the night?

 

[ferraiolo1]

mine did the same thing, it goes away after a few days.

 

[Dbowles24]

The vent line isn't plugged up. The fuel comes out of the line regardless of when I last filled up so I thought that was odd. It's been doing it for about 2 weeks now (since I got it). Yours stopped after only a few days?

 

[Max Kool]

How much is it anyway? And what's the day/night temperature where you live?

 

[ferraiolo1]

is it more than a drop?

 

[Dbowles24]

Temperature is 60s day, 50s night in northwest Washington. The cardboard shows three different days of drips.

 

[Max Kool]

Ohh, I think that's simply condensation.

 

[Dbowles24]

Ah okay, well now I feel dumb. I figured condensation would evaporate off and not leave a stain on the cardboard.

 

[Max Kool]

Don't feel dumb.

Unlike a few decades ago, fuel tanks can't breathe through the gas cap anymore, the cap is sealed nowadays. So the only option is the breather lines, where it may condensate.

Well that’s a relief. Thanks again!

Is that not the purpose of the Purge Valve which is part of the Evap Cannister System if you haven't ditched it?

 

[Max Kool]

Yes.

the vapors are absorbed by the charcoal in the canister. When the engine is running it opens the purge valve to suck the vapors out of the charcoal and burn it off. I gues on the overrun, but not sure.

 

[Dbowles24]

Mine did not come with an evap system here in Washington.

 

[Max Kool]

Nah, that’s only for CA in the US…

 

[R. Warshawsky]

That's because we have to do something to keep the air clean....never mind what these fires are doing...

 

[K9F]

I am unsure what exactly the Purge Valve purges whether it's the tank or the Evap Canister itself or both? Nevertheless not having an Evap Canister fitted doesn't necessarily mean the small valve may not still be there as it is not fitted in the canister but appears to be in the vent line?

 

[Max Kool]

The valve is not there on models without an evap system.

 

[Charliemurphay]

Yea if you don’t have the Evap Canister, you just have the vent line that tees off and goes to the front high point and the rear high point on the “U” shaped fuel tank. Nothing else on the system.

I was gonna ask where the little box was on that bike...
