So ive repeatedly taken the bike in for heat issues. Engine temps are fine however the bike is so hot you cant ride it. Ive put up with it for two years but ive had it with this lemon. It boils gas out the cap while riding. Riding gear is saturated with gas fumes to point where co-workers ask me to hang my gear down the hallway, After being burnt again i grabbed the meat thermometer and took a couple readings at the seat,   Was so hot it melted the glue holding seat to the seat pan.  So glad the dealer can find nothing wrong with the bike. Btw 67c is 156f. Talk about roasted chestnuts | ||

I was toying with the idea of fitting an XB fan into the undertray to suck some of the heat out, then I spotted this - http://www.ktmcyclehutt.com/ktm-parts/ktm-parts.ph p?sku=59035041044&title=KTM-Fan&year=&ktm-model=&c ategory=Cooling-Radiator&fitment=bigbikes I wonder if it could be adapted to fit ? | ||

YOUCH I hope you never wanted to have more kids | ||

Cant speak for anyones as mine seems to be "special" Dont know if they forgot the insulation or what but a fan wont help it. IMO its the design with the fuel in frame and heat soak, the frame becomes one giant heat sink. Bike is fine as long as it never sees any stop and go or slow riding. Soon you hit traffic break out the s'mores. | ||

yeah the frame/fuel tank thing leaves some things to be desired. last time i had mine apart i went nuts with insulating mylar tape in the inside of the frame. much much better. frame still gets warm and even hot in traffic but not nearly as bad. also helped that i remapped. all that being said last week i managed to hit 227 coolant temps on the way home official temps were in the 96deg range bikes outside air temp sensor was saying about 110ish. yes that was moving forward. and i was also not just putting around in top cog i was wailing on it. kinda wanted to see what skip spark felt like. | ||

Damn!!!! That is hot. My 08R never get close to that and I ride in 100+ temps during the summer. Some times in traffic and sometimes on the wide open road. That is nuts! | ||
| Froggy |
Nuts is indeed an understatement! Also, just because a tech can't find anything wrong doesn't mean it is "normal". I wish I knew of a way to help. | ||

Froggy Bought it in Sept 2009 and it was in shop right away for gas boiling out the over flow. Added a Cali Can due to kids room over garage and i still cant park inside for 20 minutes after riding. Its been back many times but dealer cant have mechanics ride it for 30 minutes and it takes longer then a 5 minute spin around block to get a heat soak. Now they try to blame the aftermarket fairings i installed in Sept 2011, Expect they cant explain the many trips between 2009 and 2011 for same issue. Will see what happens as im not certain HDC wants to pay for them to rip it apart and install heat shielding. Hottest i have seen coolant is 102c, AmT i have seen at 59c. I should take a pic of the gas cap.. its scary. | ||

 Comforting to know that as ride down the highway on a bike that is 156f theres fuel boiling out the gas cap saturating my clothes. | ||
| Dannybuell |
do you have pictures of your bike w/fairings? gas soaked clothes sounds bad, do you think NHTSA would want to hear about this? breathing gas fumes is unsafe! coolant temp sensor? drive your car until this is resolved? | ||
| Ratgin |
 Danny its done this since i bought it in 09. I put the fairings on in 2011, | ||

What's up with the fuel vent not doing its job? | ||
| Froggy |
If the fuel does expand, it should go right out the vent tube to atmosphere, or in your case the carbon can then motor. Obviously something is amiss here, the gas cap is sealed, if gas is able to get out, you can bet that water can get in. There really is something major wrong with your bike. | ||

Gas cap (the seals or O rings) could very well be bad. I remember when my old Granada's radiator boiled over one summer. It ended up being a bad radiator cap. Something to do with loss of pressure and a lower boiling point.?.? | ||

I had a hot bike/ gas boiling issue on my '08 in 08, and after the dealer had it for over a month, and worked with a factory engineer to help diagnose the problem, it was determined the tank vent was bad. They replaced the vent system and the charcoal canister, and this resolved the problem. It seems when the vent system is not working properly, it allows pressure to build in the frame/tank, causing an assortment of problems, most notably fuel boiling and excessive heat. i however removed my charcoal canister as to allow the system to breathe better. There is some minor but noticeable fuel smell for a short period after shutdown, but I don't worry about the charcoal canister plugging and causing vent issues. Not that I know that that happened, but I figured I'd remove that variable from the equation. Hope you get the problem fixed. | ||

4 years later, I just rode for over an hour, some stop and go town traffic and some backroads, in 102 f degree temps a couple weeks ago, and had no issues. When the bike was having these issues, it barely needed to be warm out for problems to start, and the bike was nearly unrideable on a hot day. Fuel stench, erratic running, and I don't remember what else. You could hear the gas boiling away in the frame, and the stench! It was scary! | ||

BB Mine has boiled gas from day i bought it in 2009. Put the can of as it didnt dribble out the vent hose it ran the full tube till it stopped boiling. Couldnt have that with garage. Give you an idea how bad this bike it.. in 2009 tween April and Sept i put about 10000kms on my Harley. Since Sept 2009 and now i have 8000. So far this year ive gotten to ride for 2 weeks. Been down for rest the time. Anyone have a photo of the frame insulation? Is it visible with the airbox off? Im wondering if i got a friday bike and no insulation.

I'm just sayin'... No boiling now. Not ever, since the venting issues were addressed. Use to fill that cali catch can right up with gas when it had the problem. The vent was not just non-functional. It was some sort of intermittent or partial problem. It was very difficult and lengthy for them to diagnose. The dealer replaced all the parts in the vent system, and the problem was resolved. I suspect it was the actual check ball vent piece at the top of the frame by the filler cap that the vent hose which rides under the outer airbox cover attaches to. I imagine this might be a not too expensive or difficult part to replace, even in a "throw parts at it" mentality which could well cure your bike's problem. Or possibly not. But if it did, how happy would you be? First year I had my bike the dealer had the damn thing as much as I did, so I have felt your pain. | ||

Is your tank vent clogged? It should not be coming out the cap, if anything it should come out the vent line. | ||

frame insulation from Al's shop http://www.americansportbike.com/shoponline/ccp0-p rodshow/16130.html (Al may be on his way to laguna for the MotoGP - chk his "home page" for details) Pictures - go here scroll down about the 6th pix http://www.badweatherbikers.com/buell/messages/290 431/581217.html | ||

Red No idea i have the Cali can. Nuts Perfect.. checked mine and its there. | ||

You definitely have a problem with fuel not venting properly. It should not boil over the gas cap. The Fuel boils on the 1125 frame INSIDE. It does not boil over. I put the frame insulation on and boiling gone. I do not smell like gas after a ride...any ride on my 1125R. The only time fuel spilled from my bike was when I overfilled the tank and the excess went to the Cali catch can and released it onto the ground (but not before it hit the passenger footpeg first). But that is the normal way for it to get rid of excess fuel in the fuel tank. Fuel coming out of the fill cap is NOT normal. | ||

I think it has melted a bit, the plastic piece above the oil dipstick. I wonder hot mine gets, heh didn't even notice the heat.  (Message edited by 1125rcya on July 22, 2012) (Message edited by 1125rcya on July 22, 2012) | ||

Your cali can must be clogged. Insulate the inside of the frame. You don't even need to lower the motor. I used dynamat extreme, which is very easy to work with and slide up between the frame and motor. It's thick and reduced a lot of frame heat on my bike. If you have the stock ecm, get rid of it and get the ebr. | ||
| Rogue_biker |
Here is my frame after I put the heat insulation on. Note that the engine is rotated on this photo. It took me a mere 30 minutes to measure, cut, and paste the insulation on. Fuel boiling inside the frame on a hot day eliminated.  | ||
| Ratgin |
 ive got the heat shield but since day one its boiled fuel. The cali can was added to stop it from pouring a puddle of raw gas into my garage. It didnt drip it pee'd fuel like a dog on a fire hydrant. Im to take it to shop again but im thinking its pointless. | ||
| Zac4mac |
Something is real wrong with your fueling/timing. I live a lot further south than you and I've never had issues with boiling/ejecting/peeing fuel. I did give up on OEM maps for a year or two but went with a race ECM when EBR first put them out. My motor has internal issues now so she isn't getting ridden until I can tear the motor down and rectify. Good luck with yours, I know you've had a ton of trouble. Z | ||
| Rogue_biker |
Ratgin, did you check the fuel venting system in your tank to make sure it is working? Fuel expands with heat and all fuel tanks have relief vents to allow this expansion to occur. It seems like this is the most logical culprit, and it could be that simple. | ||
| Sir_wadsalot |
Yeah, I've seen this before, it's fuel system venting. I know a guy with a KTM Super Duke. Did it from week one, they replaced his fuel tank/EFI...twice. It was common on first gen Super Dukes. That's not normal it's broken and dangerous as hell. | ||
| Uh60crewdawg |
This may sound retarded but ive seen it. The cali catch can is a one way flowing system. and many manufacturers ive seen make them so simply that one could potentially install it up side down creating a complete clog in your venting system give the fumes no where to go etc etc the rest has been said i have a 1125 with a completely custom cooling system. i need to do a write up to show it off one of these days but essentially im running the gen2 felxiglass track fairings and i modded the track inner pods to accept the fans. Being that i ride in 100+ weather i was still concerned about the cooling issue So i wired my fans to both operate together at operating temp. As oppose to stock where the second fan doesn't turn on until the temp reachs 210-220 range That with engine ice and a insulated frame I seem to run 5-10 degrees cooler than my buddies 1125 which is stock with the exception of the exhaust we both run ebr ecms'd Barkers |
