Hello Riders,

Observed this for the first time yesterday on a morning ride after a fuel refill.

Saw fuel dripping from an almost hidden 'rigid' hose pipe on the left side under tank. I am attaching a picture of the hose pipe. The fuel was dripping on to the cylinder head.

1. Is this a breather pipe for pushing out excess fuel ?
2. Why is it in a location without any extended hose ?
3. Is there a missing hose (or has fallen off) ? This is the first time I noticed excess fuel., and am baffled at why is that inverted rigid pipe facing towards the cylinder head.

Bike ran absolutely fine. Rode her for 100 miles and back. so no issues after the initial constant drip.
Trying to understand what exactly is this pipe and if this is normal or anything missing and I should add a soft hose to this.

Any help or advise would be appreciated.

I had made sure that I did not overfill fuel, but may have been close. Also the temperatures in the area was about 85 degree Fahrenheit. , so not sure if there was expansion.

thank you

You've lost a pipe.
I think that's the one that would have gone to the charcoal cannister which captures petrol vapour from the tank.
If you over fill the tank raw fuel can run through there. Not good for the charcoal cannister though.
Lots of people remove the evap system and cap off the pipes.

Thank you. Not sure how I would have lost the hose, maybe with all the vibrating

So, making absolutely sure that I only keep the tank 3/4 full (never overfill), will avoid having this problem at the first place I would envision.

Can I ignore the canister function totally ?
or should I figure out a way to route a hose to the canister ? I have to locate the canister first.

thanks again

RE tubing is generally made out of congealed curry and it's not unusual for it to deteriorate and fall off. This is why my Himalayan has a length of plastic pipe (the same stuff you'd use in an aquarium) to do the same job.

I haven't looked at the evap system on my 500 but I removed it completely on my Himalayan with no ill effect and the elimination of the back firing I was getting with the different exhaust. If you want to remove the evap system, I strongly suggest that you research it first, especially as you're not going to get any real performance improvement on these motors.
