2014 R1 Engine temp high

A few months ago I purchased a new '14 R1. I previously owned an '06 R1, and might I say, this one is a beast to be reckoned with. I have been riding it consistently since March, but now that summer is in full gear, I have had some questionable experiences concerning the engine temperature. I am 4,000 miles in and on a 85 degree+ day when I am city riding (stop and go, low speed) the temp can get as high as 234 degrees Fahrenheit and then work it's way back down to the 210's. But if I kill the engine at a light or gas station, it, at times, will go in the 240's and the red engine temperature warning light comes on. Once I ignite again it works the temp back down. So my question is, is the normal activity or cause for concern, even though the fans kick on and bring it back down. Seeing that red light on a new bike makes me nervous, being that I never saw it on my '06. If anyone can be of some assistance, that would be a great help. I'm purchasing Engine Ice as soon as I post this.

it is relatively normal, this engine does run a little hot. what some folks have done is get their ecu flashed so the fans come on earlier as at this point they only kick in at 210F. as you have
noticed, it would be best for them to kick in at 195 or so... Ecunleashed was not able to do this for me early on so i'm just installing a switch so i can control them manually and I will likely
get better fans to help with it.

Now a quick explanation of what you're experiencing, as the bike is powered up and engine running, coolant is being passed from the radiator through the engine n' back and because the fans kick in this allows for the temps to drop as you're sitting at the lights, rad cools down thanks to the fans, and coolant cycling does the rest of the magic.. Once you get going and wind cools down the rads even more which brings temps down further and so on... If you turn off the motorcycle you are taking away the ONLY means of it to get cool down so of course temps are gonna shoot up and you can get a red warning light... for this same reason NEVER leave the fans on if you are not running the bike cause all they will be doing is essentially blowing hot air right back onto the engine, there is not much room between the engine and the rad to begin with and if there is no cycling of coolant then you're not doing a thing but heating the engine back up with its own heat, make sense?. The fans only really do their thing if the system is operating and fresh coolant is being brought into the engine from the rad. which is being cooled down by the fans.

I am running ENGINE ICE and it does help to bring temps down a good 5-10deg. F. which may not sound like much but believe me at those temps it really is... i run in the low 170s all day long with some spurts of mid 180s on average, if its cool out i can get down into the 160s which is bloody great! without engine ice i was consantly deep into the 190s and so its pretty easy to see how you would be hitting 220s very quickly once you stop at lights... word of advice! this is not really a stop and go motorcycle, i hate riding in town for the most part.

no worries, i did you a favor and rode through traffic and a few lights today, yup temps shoot up in the 190s rolling around, at lights it goes to 220 but it quickly comes down, used to go higher before engine ice. which is why track guys dont see much difference, once in the paddock no matter what she's gonna be toasty :yesnod

now cruising on freeway with medium temps like 70s or so she's happy at low 170s all day long

my bike runs insanely good in the 176 - 186 def. F ranges. shes extra responsive. i love it :lol
yeah she's happy right there... its very obvious how much better she runs at those temps

Engine Ice is a good clean coolant.
yup, in regards to the stigma mentioned above it has a lot more with which one is allowed at tracks and such, but folks mix the two up regularly :shake

from what i've read Engine Ice is widely accepted at most tracks, where watter wetter is not, and where it is everybody swears engine ice sucks; only cause its not allowed go figure :dunno

my R1 is a street bike so i run whatever the fvck i want :hammer:

I don't have a garage so my bike is stored outside in a makeshift cocoon. I'd hate to have to swap in different coolant just for winter every year simply to get the Engine Ice out... huge PITA.
see, i've read the exact opposite, i have no idea which one is right but my bike sits all winter with last season's engine ice and i have had zero problems...

i did do a flush with distilled water this year and it was not really filthy as much as it was very green, tell tale of being in need of replacement, its blue out of the bottle when new..

i live in Canada by the way, no issues in spring whatsoever :no

Hottest time for an engine is the immediate minutes after it's been shut off. Lots of stored heat that isn't being transferred to water.

Are there any negatives or risks to using Engine Ice? I seem to remember associating a negative stigma with that stuff.... possibly not good for use in a bike that might see occasional temps below freezing? I may be confusing it with Water Wetter.
