Was wondering if anyone else has been having this issue Got bike back from stator fix. In stuck traffic and air-box temp reading was 56c (130ish F), Coolant temp was normal bouncing from 85-99c. Frame got so hot it was burning my legs through riding pants. Melting boots onto the swingarm Got home shut it off and fuel was boiling like crazy. An hour later it had filled the garage with so many fumes it seemed like it would detonate with an ignition source. This bike has the cali ca, Today was a repeat. CT 85-99 , Air-box 54c but the engine light came on. Nursed it home and light switched off after about 15 minutes. Turned key on after parked for 30 minutes and CT was still 95c. Why is it so damned hot? CT seems normal, bike sounds fine but is so damned hot you cant ride it. Just a guess but i figure the frames in the 150 plus F range. | ||

sounds like its running very lean. Others have posted about this problem dont remember how they resolved it do a search and see what you find Froggy Do you remember? | ||

How hot was it outside? Stock or Race ECM? Are the fans working? They shouldn't be getting that hot under normal conditions, but if you are stuck in traffic on a blazing hot day, the hot cars and tarmac aren't helping. | ||

I have to agree with the lean comment. I have a PCV w. auto tune on mine right now and have it set to 13.8 at 5-20% throttle. I ride mostly highways so with wind a bit of heat from lean fueling seemed like a good deal. I am in the 40c range alot now. I'm planning to reset it to 13.2-3 and see how that changes things. Sorta sad cause fuel economy has been great.  | ||

I have been using 93 Octane gas all along. This week, I put in 91 Octane gas on my 09 1125CR for the first time. By bike now appears to running cooler. Normally it goes to 190's-200's when stopped (summer time in DC). It was only running in 180's. Don't know if it's weather related or 91 Octane actually helps running engine cooler. Anyone have any thoughts on Octane and temperature? | ||

latest flash, stock everything engine related fans working fine hot for Canada (86f) not anywhere else 91 octane ethanol free bike runs great just too hot to ride it. It has always been hot from day 1. figured it was a qwerk of the bike but since the stator fix (post moke pouring out of bike) its now insane. airbox sems 130f in any kind of inner city ride. ct is 185-210f which seems normal.

In my experience, the 1125 is essentially unrideable when the temps get above about 80 F out. My bike is running fine, I have ceramic coated headers and the race ECM. The SOB is just freaking hot and uncomfortable when not moving. | ||
| Dannybuell |
Freight_dog -What did you notice after the ceramic coated headers went on? | ||

Fuel has minimal effect on engine heat. Ignition timing has a larger effect. Just the way engines work. You can get bright red headers "just" by lowering the timing..! I raised my timing along with the fuel... Yesterday it was in the mid/upper 90's on the way home from work. My CR never got above 190F, even at a sorta long signal. Since I started my mapping quest (finding what the engine wants!!), 202F on a 100F+ day is the highest I've seen. Mike | ||

Certainly the headers are a lot cooler. I still get a lot of heat on my right boot from the exhaust, probably more than before due to the exhaust exiting at my boot instead of the swingarm, but the headers are cool to the touch almost immediately after shutting down. Most of the heat that affects me seems to be engine heat transferred to the frame. I have the FMF full exhaust without the heat shield the stock headers have, but I find that to be no problem with the coated headers. Mine is an '09 and there is factory applied heat shielding on the inside of the frame. (Message edited by Freight_dog on July 09, 2011) | ||

210 is hot. Check your coolant, make sure you're full. I have, however, ridden (and sat in traffic) in 95 degree weather with CT hovering between 202 and 212...and it was NOT "unrideable". And that was in mesh Joe Rockets - pants and jacket. Put your toes all the way on the outer ends of the pegs. Open your knees away from the bike. An inch makes all the difference in the world. | ||
| Luisemilio25r |
that's what she said  sorry couldn't help it! | ||
| Ratgin |
Rat Ive same CT as you but airbox temp was 56c/130 so the frame was likely another 20 degrees hotter, it was enough to melt my riding boots where the heels touch the swingarm and burn me through my riding gear, ive added a bit more coolant and will try it again. Like i said it ran fine, ct were "normal" but the engine light came on so something isnt right | ||
| Zac4mac |
I don't understand how the swingarm is melting your boot. Nothing in it on the 1125s, this is not an XB with oil in the swingarm....??? Z | ||
| Ratgin |
Zac4mac That's how hot the damn frame is.. it doesnt make any sense, CT is ok, Airbox/frame temps are insane wonder if mine was never insulated? And if CT is ok then why is the engine light coming on. (Message edited by ratgin on July 10, 2011) | ||

I am trying to stay out of traffic in the heat on motorcycles. The CR is the same way. As mentioned above, "Put your toes all the way on the outer ends of the pegs. Open your knees away from the bike. An inch makes all the difference in the world". | ||
| Ratgin |
Yup that works to save skin but not the engine. I got out of the traffic jam quickly but even normal traffic lights is an issue with temps. The engine light came on during regular urban traffic (stop lights). | ||
| Blake |
How does a hot frame cause the swingarm to get hot?  What is your VIN, and who is your dealer? PM me if you prefer. Just need to confirm that you are not some kind of internet troll. What you are claiming is tough to believe. Over the years, we've had too many trolls invade the site spouting nonsense; just want to be sure you aren't one of them. As long as your coolant temperature and oil are okay, the engine is at no risk. | ||
| Blake |
Sounds like your dealer did something to mess up the bike when they performed your stator work. I'd be returning it and asking that they resolve the problem. | ||
| Ratgin |
Its going back tomorrow Blake. Vin is on my registration. No idea why frame and swingarm are so hot, its why ive asked for help Its bloody odd that the engine light comes on but max temp ive seen for CT is 99c. Makes no sense unless the engine light is unrelated to the heat issue. | ||
| Boogiman1981 |
may just be a personal preference thing for the heat. i've been in more stop than go traffic and have seen coolant temps hit 220 and sure it was hot yep the gas was boiling but no 'for me' it wasn't to hot to ride. given that the engines aren't failing do to heat (granted stators it would seem are) i think that the 'to hot to ride' part is more about personal comfort zone than anything else. having said that by all means have it checked and please if the dealer or you should come across a specific reason why it was/is running that hot let us know that we might check ours as well. | ||
| Jules |
And if CT is ok then why is the engine light coming on What code does it throw? | ||
| Freight_dog |
Put your toes all the way on the outer ends of the pegs. Open your knees away from the bike. An inch makes all the difference in the world. I didn't say it was completely unrideable, just "essentially". If you have to take a special riding position to make the heat tolerable, it really takes the fun out of riding, and the 1125 is frustrating to ride, "FOR ME" when it gets above 80ish degrees out. | ||
| Blake |
The fact that there was a drastic change after having service performed indicates a possible problem/issue that is worth trying to resolve. The muffler is close to the swingarm, so maybe it is getting heated from that, but enough to melt the sole of a boot? That just seems really tough to imagine. | ||

My 09 CR gets VERY hot when the outside temps are up. Similar to what you are saying. I have arrived after a short ride (~20 mins) and the inside of my legs have been cherry red from the heat through my jeans or riding pants. The weird part to me is that this heat issue does not seem to correlate to the engine coolant temp on my bike. There are days when 180 on the CT display will burn me alive and there are days when 200 CT doesn't bother me. I can find very little repeatable fact. Sometimes the bike is enjoyable...sometimes it is scorching. ac | ||
| Boogiman1981 |
Avc on the days it bothers you is it both legs or just one? i ask if maybe it's sun exposure to one side or the other. these things get hot quick in the sunshine do you notice on the bothersome days more stop and go or less? heat soak even at a lower temp in lower ambient temps if you're sitting still more the frame/tank is gonna get hotter than moving with higher coolant temps | ||
| Ratgin |
Boogiman Mine is certainly heat soak. On highway it isnt bad but stop at a light/traffic and ct will rise to 99c, but frame will not cool after that. An hour later the frame heat will keep the ct at 95c both sides and seat burning hot through riding pants. I cant ride it in jeans, wonder if my bike is missing the frame insulation. | ||
| Avc8130 |
Mine is just like Ratgin. Mine has the frame insulation. I am not convinced the frame insulation is a good thing. It greatly reduces air flow between the motor and the frame. Once the insulation and frame are heat soaked...there is nothing insulation can do to help. ac | ||

My 1125's frame gets really hot if I spend any time in traffic--to the point that it is uncomfortable for my legs to touch it through jeans. It sometimes does feel hot enough that if I pressed my legs against it, it might burn them. Much of the engine heat radiates into the frame, and if the bike sits stationary or is ridden at low speeds, the frame will heat soak to the point that it gets really hot. The fans pull air through the radiators and onto the engine (and in between the frame spars) which also contributes to things getting hot in there when not moving. Now I've never had this be a problem if I only have to make short stops for lights. Today it's currently about 95F--I rode to lunch about 7 miles down the road, mostly at around 70-75mph with a few stoplights and a mile or two of 50mph in-town stuff. Coolant temp stayed around 177-180F and the frame didn't get especially warm. Same thing for the ride back 30 minutes later. (I've got an '08 with the Barker exhaust and matching EB R ECM.) In short, I don't think there is anything out of the ordinary with the OP's bike. Actually, come to think of it, I only got the EB R ECM a few months ago and I haven't had the frame get really hot on me like it did last summer. But I also haven't spent any time stuck in traffic this summer either. Does the EB R ECM help keep the frame cooler? Probably. (Message edited by thefleshrocket on July 11, 2011) | ||

When it's hot and sunny out, the surface of the street, a vehicle's roof, or just about anything not painted pure white or finished in chrome, will be scorching hot. Anything over 120oF feels burning hot to the touch to a human. How some expect a running high performance motorcycle to remain cool in such conditions while parked over scorching hot pavement is, well, odd. HTFU amigos. Some of the statements being made here are really hilarious, typical internet expertationizing proclaiming new laws of physics and the news flash that during the heat of Summertime, stuff can get really hot.  >>> Once the insulation and frame are heat soaked...there is nothing insulation can do to help. Insulation reduces the transfer of heat energy across it's thickness no matter the temperature it reaches. If the heat which is causing the frame to get hot to the touch is coming from the engine, the insulation between the two will reduce the rate of heat transfer and thus the temperature of the frame. >>> Mine is certainly heat soak. On highway it isn't bad, but stop at a light/traffic and ct will rise to 99c, but frame will not cool after that. First, an engine coolant temperature of 99C is normal and perfectly acceptable. How can the frame not cool if re-exposed to highway speed cooling airflow? For it to not do so violates the laws of physics. >>> An hour later the frame heat will keep the ct at 95c The frame does not affect engine coolant temperature. A coolant temperature of 95C is perfectly normal. >>> both sides and seat burning hot through riding pants. I cant ride it in jeans, The same thing happens to any motorcycle just sitting out in the sun. Black seats get hot when exposed to the 1.2 KW per square meter of summertime sun energy incident upon it. Go figure. If I forget to put up the sun shield in my truck, the steering wheel gets so hot I can't touch it. I have to start the truck and let the AC kick in for a while before I can drive off. You can literally fry an egg on hot pavement solely due to the energy imparted by the sun. Are we men or boys? Young little boys with tender skin ought not to be riding big bad mean motorcycles period.  Seriously guys, let's try to keep it real. (Message edited by blake on July 11, 2011) |
