I posted on the site last year when I was deployed and purchasing my 08 1125R. Got to ride it 1 day last year when I got home before it snowed and I had to park it. I came out to Southern Arizona last month for a military school and have gotten to actually enjoy the bike. Now, I did plenty of research before I purchased the bike, but somehow missed all the posts about the boiling fuel issue. (yeah great job Intel Analyst) The bike does have the Cali Can installed but it still concerns me because it has only barely topped 80 here. I'm wondering how bad of a problem this will be when the temperature tops 90. When I pull the fuel cap it hisses pretty good and I'm worried about building too much pressure. Any suggestions about coolant or other solutions would be appreciated. The bike has the Keda RT-3 and EBR Race ECM installed. I love the bike and have no real complaints other than this issue. Also, does anyone make a MotoGP style rear hugger? I've seen one on the Ilmberger prototype but haven't found any in production. Love the look and think the lines go great with the swingarm. | ||

I have two in Az too that I get to periodically visit between other trips and assignments here and there. I've ridden it from freezing to 118. The air temp reading has been as high as 156 sitting at the lights. The fuel boil problem is definitely present but shouldn't be a significant problem so as to pressurize the tank when you pull the gas cap. It is normal, though, to drip out the vent tube (or in the can). If it is building that much pressure, you have to think that the hose is restricted somewhere. Mine did one time after removing the airbox and twisting the pliable part of the hose when putting it back together. Straightened it out, no pressure buildup. Always drips though. You can line the inside of the frame (heat shield available from American Sportbike or elsewhere, and that helps too. But the problem shouldn't be the level you describe. | ||

I'd check the gas tube hose and make sure yours isn't pinched along the way back to your Cali can. Hissing isn't normal when removing the gas cap for a refuel. There will be a constant drip of fuel, not a puddle, on hot days from the vent tube until the fuel cools. I don't have the Cali can, but see mine dripping on hot days. The vent tube exits on the rear left side of the bike. | ||

Your Cali can could very well be plugged. I had one put on by the dealer early on, it eventually failed. I went back to the drip line method. The one thing I have had to learn is not to overfill the tank. I think this overwhelms the Cali can and drip line emissions. | ||

I agree with Dannybuell, don't overfill. Fill to about an inch from the top. | ||

My 2008 didn't have the problem My 2009 does Regardless of temps, or the amount of fuel in the tank, it does it often. The amount of fuel is minor, I just ignore it | ||

Fuel boil can be an issue from time to time, but - it can be easily mitigated. I did what Ljm did (line inside of frame with heatshield stuff) on my race bike, and I almost never top the tank. This bike gets run HARD, has no cooling fans and gets to 200 plus degrees sitting on the grid. I've had not fuel boil since lining the frame. With that said, vent tube pinching or blockage can be a BIG deal, especially if fuel is hot and you open the tank cap - I got a face full of knowledge on that one, trust me - no bueno. The 2008 1125 has been very dependable in my experience and a little vent drip from time to time is no biggie compared with some of the problems with other bikes. | ||

Thanks gentlemen. All signs are pointing to the Cali can being clogged. I went for a little ride tonight and got the bike to about 175 and when I got home I could hear the boil. I checked the lines all the way back to the can and nothing was pinched so I pulled the line at the can and it was hissing. The new question is what should I do about the can? Is there a way to unclog it or do I need to find a new one or go to a different set up? | ||

do a drip line like the other 48 states by extending that line out to behind and below the left rear foot peg bracket. let it drip from there. | ||

I never got the Cali can. I did get the recall that re-routed the drip line to the rear pass. peg. Loretta started pissing every ride... So I re-re-routed the line to its shorter original route and no more pissing. Original drip point was to the front of the clutch-puck. Works for me. Zack | ||

Zac4mac are you using the inner air box? | ||

Just finished fixing the beast. I had filled the gas tank right to the top and let it sit out in the sun a few hours on a hot (26C) day. On start up it backfired and basically wouldn't run at all. Found the throttle bodies blown completely off their rubber sleeves. Put everything right and it's happy and ready to ride. | ||

Sorry Danny, Haven't checked in, in a couple of days... Yes, K&N filter/inner air-box/outer air-box. I figured, in my case at least, that the longer hose was allowing the fumes to condense. I expect I still emit vapors from the vent line, but no puddles. Zack |
