I have a 49 state version 1125cr. That means it came without the charcoal canister that California models get. When I first took ownership, when I'd park the bike and it was hot, gas would drip out of the overflow tube on to the floor leaving a puddle in the garage and stinking up the house. I installed a charcoal canister which stopped the dripping but did nothing to alleviate the smell. Now, virtually every time I park the bike it stinks up the house.

My question to you guys is has anyone figured out a way to keep these things from overwhelming their environment with gasoline fumes?

Park it outside until it cools? : D

Eliminate the heating of the fuel tank/ frame. The fuel tank is exposed to radiator waste heat and radiant heat from the engine, all without any insulation.

you may be overfilling your gas tank. the frame/tank gets hot and boils the gas out...

from way back, EBR was recommending the aerogel product.

Thanks.

I do park it outside when I can : )

The '09s came with insulation on the inside of the frame. It's not full coverage but it covers most of the inside. I had considered adding more next time I adjust the valves so it'd be fully covered.

I've tried not filling it up completely to see if that had any effect. It doesn't. Even if I leave a couple inches below the filler neck it still has the same stink. It also does it whether the tank is full, half empty or almost completely empty.

Is this common? Does everyone else's have the same behavior? I know there's a check valve in the fuel tank where the overflow comes out. I wondered if mine might be misbehaving. Do you guys experience the same thing?

my 09 CR has no insulation. they did the cannister for me when I asked for it. It didn't do anything but make it run rough.

ceramic coating the headers should keep a lot of heat away from the frame...

the side pod fans direct hot air to engine.

The primary air inlet is just after the front exhaust header...

The air box setup keeps the lid on everything and thus keeps heat in...

There are aftermarket airbox cover designs that have forward vents. They are assuming the air box is removed for more air circulation than the forward inlet...

Pwillikers, my 09 does everything you describe. When the dripping through the overflow vent is particularly bad, I just loosen the fuel cap and the dripping stops but the fumes are still there. I find even when the tank is almost empty, mine still drips fuel. Parking it outside for 15 minutes after riding is for me the cheaper and best option.

Thanks Joe, so it's not just mine.

I'm sure the quantity of vapors produced by the tank vent is overwhelming the absorption capacity of the charcoal canister. I can think of no way to alleviate the issue - just another quirk with which to live. :-)

My 2008 1125R didn't do it at all

My 2009 1125R likes to piddle and mark it's spot all the time. Temperature, fuel level, none of it seems to be a factor. If the bike is warm and has been run, it takes a leak when it's parked.

Treat it like a turbocharged engine - don't go from full-tilt-boogie riding immediately to turning it off. Ride gently for a bit before parking, let it cool somewhat. The theory on turbocars is, it circulates oil through the turbo bearings to prevent coking (boiling the oil to the point it turns to carbon).

I treat my CR this way, and either the fuel smell doesn't bother me (it's a machine, after all...)...or the method works.

And I have yet to see liquid fuel dripping out my overflow tube.

I'm thinking about running a discrete catch can to the breather line. I have the same gas problem with my 1125cr and when I ride to work I have to park my bike inside my work place. I figure if I can find a way to mount a small catch can with an empty valve, the gas can collect and I can empty it prior to my ride. I'll let you guys know how it turns out.

Have you tried lighting a match to get rid of the fuel smell?

I put a fan in front of the front wheel, pointed toward the engine. It seems to work for me when I can't leave it outside to cool down.

I put the canister and insulation on my 08.
No more drip and really reduced the smell(down to about what my firebolt puts out).
However, hot restarts became a problem do to the canister flooding the intake with all the fuel vapors. Nothing major but you had to crank on it for awhile to clear it out.

My stock,non-insulated 2008 didn't do it

My stock, insulated 2009 does it


- I think a fresh tank with less than a couple miles on it won't do it
- riding gently for the last few miles has no effect
- fuel level has no real effect

I've just embraced it. I tell people my bike's just marking it's territory
